Large storms and periodic earthquakes are responsible for most of the documented seacliff slope failures.

Research suggests that more erosion occurs along the California coast over a short time scale, during periods of severe storms or seismic activity, than occurs during decades of normal weather or seismic quiescence (Griggs and Scholar, 1998; Griggs, 1994; Plant and Griggs, 1990; Griggs and Johnson, 1979 and 1983; Kuhn and Shepard, 1979).\r\n\r\nThis is the second map in a series of maps documenting the processes of short-term seacliff retreat through the identification of slope failure styles, spatial variability of failures, and temporal variation in retreat amounts in an area that has been identified as an erosion hotspot (Moore and others, 1999; Griggs and Savoy, 1985). This map presents seacliff failure and retreat data from Seacliff State Beach, California, which is located seven kilometers east of Santa Cruz (fig. 1) along the northern Monterey Bay coast. The data presented in this map series provide high-resolution spatial and temporal information on the location, amount, and processes of seacliff retreat in Santa Cruz, California. These data show the response of the seacliffs to both large magnitude earthquakes and severe climatic events such as El Ni?os; this information may prove useful in predicting the future response of the cliffs to events of similar magnitude.

The earliest set of photography is from 1989, taken immediately following the Loma Prieta earthquake. These photographs are used to document the response of the seacliffs to seismic shaking, as well as to establish a baseline cliff-edge position to measure the amount of retreat of the cliff edge over the following decade. The remaining three sets of photographs were collected using the U.S. Geological Survey Coastal Aerial Mapping System (CAMS) during the 1997-98 El Ni?o (see Hapke and Richmond, 1999; 2000).

This map presents sea cliff failure and retreat data from the Seabright Beach section, California, which is located on the east side of Santa Cruz along the northern Monterey Bay coast. The data presented in this map series provide high-resolution spatial and temporal information on the location, amount, and processes of sea cliff retreat in Santa Cruz, California. These data show the response of the sea cliffs to both large magnitude earthquakes and severe climatic events such as El Ni?os; this information may prove useful in predicting the future response of the cliffs to events of similar magnitude. The map data can also be incorporated into Global Information System (GIS) for use by researchers and community planners. During this study we developed a method for investigating short-term processes of sea cliff evolution using rectified photographic stereo models. This method allows us to document the linear extent of cliff failures, the spatial and temporal relationship between failures, and the type or style of slope failure.\r\n\r\nSeabright Beach extends 0.9 km from San Lorenzo Point on the west to the Santa Cruz Yacht Harbor on the east. The cliffs at Seabright Beach are completely protected from wave attack by a wide beach. The protective beach is a relatively recent feature that formed after the emplacement of the Santa Cruz Yacht Harbor jetty in 1963-1964. Prior to the completion of the jetty, the cliffs at Seabright Beach were subject to daily wave attack. The data in this study are post-jetty construction; therefore, the sea cliff failures and cliff retreat are the result of nonmarine processes (rainfall, groundwater and seismic shaking). The 8 to 15 m high cliffs at Seabright Beach are composed of the Miocene to Pliocene Purisima Formation, which is overlain by unconsolidated Pleistocene terrace deposits. The relative thickness of these units varies along the length of the cliff. At the west end of Seabright Beach, including San Lorenzo Point, nearly the entire cliff section is composed of Purisima Formation and is capped by less than 2 m of terrace deposits. In this exposure, the Purisima Formation is a moderately weathered, moderately indurated massive sandstone. The height of the cliffs and the thickness of the Purisima Formation decrease to the east. In the cliffs immediately adjacent to the harbor, the entire exposure is composed of terrace deposits. Toe-slope debris and wind-blown sand form a nearly continuous fan along the cliff base that obscure the lower portion of the cliff.\r\n\r\nThis study documents the impacts of earthquakes and large storms to the sea cliffs in the Seabright Beach section. The first event is the 1989 Loma Prieta earthquake, a M7.1 earthquake that caused widespread damage to the area stretching from Santa Cruz to the San Francisco Bay. The epicenter of the earthquake was located in the Santa Cruz Mountains, approximately 9 km inland from the coast.

The quadrangle covers an area of the Mojave Desert characterized by desert ranges separated by broad basins. Ranges include parts of the Old Woman, Ship, Iron, Coxcomb, Pinto, Bullion, and Calumet mountains as well as Lead Mountain and the Kilbeck Hills. Basins include part of Ward Valley, part of Cadiz Valley including Cadiz Lake playa, and broad valleys occupied by the Bristol Lake and Dale Lake playas. Bedrock geologic units in the ranges range in age from Proterozoic to Quaternary. The valleys expose Neogene and Quaternary deposits. \r\nProterozoic granitoids in the quadrangle include the Early Proterozoic Fenner Gneiss, Kilbeck Gneiss, Dog Wash Gneiss, granite of Joshua Tree, the (highly peraluminous granite) gneiss of Dry Lakes valley, and a Middle Proterozoic granite. Proterozoic supracrustal rocks include the Pinto Gneiss of Miller (1938) and the quartzite of Pinto Mountain. Early Proterozoic orogeny left an imprint of metamorphic mineral assemblages and fabrics in the older rocks. \r\n\r\nA Cambrian to Triassic sequence deposited on the continental shelf lies above a profound nonconformity developed on the Proterozoic rocks. Small metamorphosed remnants of this sequence in the quadrangle include rocks correlated to the Tapeats, Bright Angel, Bonanza King, Redwall, Bird Spring, Hermit, Coconino, Kaibab, and Moenkopi formations. The Dale Lake Volcanics (Jurassic), and the McCoy Mountains Formation of Miller (1944)(Cretaceous and Jurassic?) are younger Mesozoic synorogenic supracrustal rocks in the quadrangle. \r\n\r\nMesozoic intrusions form much of the bedrock in the quadrangle, and represent a succession of magmatic arcs. The oldest rock is the Early Triassic quartz monzonite of Twentynine Palms. Extensive Jurassic magmatism is represented by large expanses of granitoids that range in composition from gabbro to syenogranite. They include the Virginia May Quartz Monzonite and other members of the Bullion Intrusive Suite, the Chubbock Porphyry, and rocks that form the Goat Basin pluton, Music Valley pluton, and Ship Mountains pluton. The Jurassic plutons range in emplacement depths from mid-crustal to hypabysasal. Mafic and felsic dikes that probably are part of the Late Jurassic Independence dike swarm intrude the Jurassic batholithic rocks. \r\n\r\nA Mesozoic ductile fault (tectonic slide), the Scanlon thrust, places an inverted sequence of lower Paleozoic rocks and their Proterozoic basement over a lower plate of younger Paleozoic and Triassic rocks. The lower- plate rocks are internally sliced and folded. They in turn are superposed along an attenuation tectonic slide, the Kilbeck fault, over highly strained tectonic schist. The major tectonic slides and associated fabrics are cut by Late Cretaceous batholithic rocks. \r\n\r\nWidespread Late Cretaceous granitoids assigned to the Cadiz Valley batholith and the Old-Woman Piute Range batholith together form a contiguous super-unit of granite and granodiorite compositions. The Old- Woman Piute Range batholith includes the granite of Sweetwater Wash in the Painted Rock pluton and the Old Woman Mountains Granodiorite forming the Old Woman pluton. The large Cadiz Valley batholith is divided into the Iron Mountains Intrusive Suite and the Coxcomb Intrusive Suite. The Iron Mountains Intrusive Suite includes the Granite Pass Granite (which forms the Granite Pass pluton), the Danby Lake Granite Gneiss, and the Iron Granodiorite Gneiss. The Coxcomb Intrusive Suite consists of many units including the Clarks Pass Granodiorite, the Sheep Hole Mountains Granodiorite (forms the Sheep Hole Mountains pluton), and the Sheep Hole Pass Granite (forms the Sheep Hole Pass pluton). The Cretaceous rocks were emplaced at a range of deep to shallow depths, and their intrusion resulted in an aureole 2-3 km wide in older rocks. Mylonitic fabrics developed through a thickness of >1.3 km, together ","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/mf2344","usgsCitation":"Howard, K.A., 2002, Geologic Map of the Sheep Hole Mountains 30' x 60' Quadrangle, San Bernardino and Riverside Counties, California: U.S. Geological Survey Miscellaneous Field Studies Map 2344, 2 Map Sheets: Sheet 1-56 x 31 inches, Sheet 2-60 x 36 inches; ReadMe: 17 p.; Data Package; Metadata, https://doi.org/10.3133/mf2344.","productDescription":"2 Map Sheets: Sheet 1-56 x 31 inches, Sheet 2-60 x 36 inches; ReadMe: 17 p.; Data Package; Metadata","additionalOnlineFiles":"Y","costCenters":[{"id":647,"text":"Western Earth Surface Processes","active":false,"usgs":true}],"links":[{"id":110295,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_51545.htm","linkFileType":{"id":5,"text":"html"},"description":"51545"},{"id":182683,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9552,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2002/2344/","linkFileType":{"id":5,"text":"html"}}],"scale":"1","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116,34 ], [ -116,34.5 ], [ -115,34.5 ], [ -115,34 ], [ -116,34 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a8448","contributors":{"authors":[{"text":"Howard, Keith A. 0000-0002-6462-2947 khoward@usgs.gov","orcid":"https://orcid.org/0000-0002-6462-2947","contributorId":3439,"corporation":false,"usgs":true,"family":"Howard","given":"Keith","email":"khoward@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":265886,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

These include:  (1) faulting that results in the juxtaposition of stratigraphic units with contrasting hydrologic properties, which may cause ground-water discharge and other perturbations in the flow system; (2) special physical characteristics of the fault zones, such as brecciation and fracturing, that may cause specific parts of the zone to act either as conduits or as barriers to fluid flow; (3) the presence of a variety of lithologies whose physical and deformational characteristics may serve to impede or enhance flow in fault zones; (4) orientation of a fault with respect to the present-day stress field,  possibly influencing hydraulic conductivity along the fault zone; and (5) faults that have been active in late Pleistocene or Holocene time and areas of contemporary seismicity, which may be associated with enhanced permeabilities.\n      The faults shown on maps A and B are largely from Workman and others (in press), and fit one or more of the following criteria:  (1) faults that are more than 10 km in map length; (2) faults with more than 500 m of displacement; and (3) faults in sets that define a significant structural fabric that characterizes a particular domain of the DVRFS.  The following fault types are shown:  Neogene normal, Neogene strike-slip, Neogene low-angle normal, pre-Tertiary thrust, and structural boundaries of Miocene calderas.  We have highlighted faults that have late Pleistocene to Holocene displacement (Piety, 1996).  Areas of thick Neogene basin-fill deposits (thicknesses 1-2 km, 2-3 km, and >3 km) are shown on map A, based on gravity anomalies and depth-to-basement modeling by Blakely and others (1999).  We have interpreted the positions of faults in the subsurface, generally following the interpretations of Blakely and others (1999).  Where geophysical constraints are not present, the faults beneath late Tertiary and Quaternary cover have been extended based on geologic reasoning.  Nearly all of these concealed faults are shown with continuous solid lines on maps A and B, in order to provide continuous structures for incorporation into the hydrogeologic framework model (HFM).  Map A also shows the potentiometric surface, regional springs (25-35 degrees Celsius, D'Agnese and others, 1997), and cold springs (Turner and others, 1996).","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf2372","collaboration":"Prepared in cooperation with the U.S. Department of Energy National Nuclear Security Administration Nevada Operations Office","usgsCitation":"Potter, C., Sweetkind, D.S., Dickerson, R., and Killgore, M., 2002, Hydrostructural maps of the Death Valley regional flow system, Nevada and California: U.S. Geological Survey Miscellaneous Field Studies Map 2372, 2 maps Sheets: 34 x 50 inches; Readme; Metadata; ArcInfo Files, https://doi.org/10.3133/mf2372.","productDescription":"2 maps Sheets: 34 x 50 inches; Readme; Metadata; ArcInfo Files","costCenters":[],"links":[{"id":180436,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf2372.png"},{"id":6045,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2002/mf-2372/","linkFileType":{"id":5,"text":"html"}},{"id":110287,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_50573.htm","linkFileType":{"id":5,"text":"html"},"description":"50573"}],"scale":"350000","country":"United States","state":"Nevada;California","otherGeospatial":"Death Valley","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.0,35.0 ], [ -118.0,38.0 ], [ -115.0,38.0 ], [ -115.0,35.0 ], [ -118.0,35.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc693","contributors":{"authors":[{"text":"Potter, C.

The map area is part of the I-70 urban corridor, which is experiencing rapid and escalating urban growth.  Geologic mapping along this corridor is needed for ongoing land-use planning.  A variety of rocks and deposits characterize the map area and areas nearby.  Sedimentary rocks present in the map area range in age from Pennsylvanian rocks, which were deposited in the ancestral Eagle basin during the formation of the ancestral Rocky Mountains, to Late Cretaceous rocks that were deposited just prior to the formation of the present Rocky Mountains.  The Pennsylvanian rocks in the map area include a thick sequence of evaporitic rocks (Eagle Valley Evaporite).  These evaporitic rocks are commonly complexly folded throughout the southern part of the quadrangle where they are exposed.  In general, in the central and northern parts of the quadrangle, the sedimentary rocks overlying the evaporite dip gently to moderately northward.  Consequently, the youngest sedimentary rocks (Late Cretaceous rocks) are exposed dipping gently to the north in the northern part of the quadrangle; landslide complexes are widespread along the northerly dipping, dip slopes in shaly rocks of the Cretaceous sequence in the northeastern part of the map area.  During the Early Miocene, basaltic volcanism formed extensive basaltic flows that mantled the previously deformed and eroded sedimentary rocks.  Erosional remnants of the basaltic flows are preserved in the southeastern, west-central, and north-central parts of the map area.  Some of these basaltic flows are faulted and downdropped in a manner that suggests they were downdropped in areas where large volumes of the underlying evaporitic rocks were removed from the subsurface, beneath the basaltic rocks, by dissolution or flowage of the evaporite in the subsurface.  Quaternary and late Tertiary(?) surficial deposits in the map area consist mainly of Quaternary alluvium and colluvium, late and middle Pleistocene terrace gravels of the Eagle River, Miocene(?) gravel remnants of the ancestral Eagle River and its tributaries, and Pleistocene to recent mass movement deposits that include landslides and debris flows.  Potential geologic hazards in the map area include landslides, debris flows, rockfalls, local flooding, ground subsidence, and expansive and corrosive soils.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/mf2361","usgsCitation":"Lidke, D., 2002, Geologic map of the Eagle Quadrangle, Eagle County, Colorado: U.S. Geological Survey Miscellaneous Field Studies Map 2361, Sheet 38 by 32 inches ( in color).

The Hayward Fault is recognized to be among the most hazardous in the United States (Working Group on California Earthquake Probabilities, 1999). This document makes available geologic evidence for historical and prehistoric surfacerupturing earthquakes that were recorded at the site. Prehistoric earthquakes deduced from geologic evidence are called paleoearthquakes. Establishing a chronology of paleoearthquakes is of immediate use in resolving the level of hazard posed by the Hayward Fault for producing large earthquakes in the future. Preliminary findings of this investigation have been presented in Lienkaemper and others (2001). A formal report on our conclusions based on these data is in preparation. The investigation at Tyson's Lagoon is ongoing, so these products should not be considered final. Lienkaemper, Dawson, and Personius interpreted the geology and logged the trenches. Seitz and Reidy performed analyses on radiocarbon and pollen samples, respectively. Schwartz led the critical-review field team.\r\n\r\nPrevious trenching work was done at Tyson's Lagoon (figs. 2, 3 on sheet 1). Lienkaemper (1992) references the location of most of those trenches. The earlier trenching was generally for the evaluation of local faultrupture hazard, except for the study of Williams (1993), which was a paleoearthquake investigation. An unpublished study by J.N. Alt in 1998 (shown on our site map as trenches 98A and 98B, fig. 3, on sheet 1), also sought evidence of paleoearthquakes. Alt's study and one by Woodward-Clyde and Associates (1970; trenches 70A to 70G, fig. 3) were located south of Walnut Avenue in one of the few areas that still remain undisturbed and were, thus, useful in planning our work in 2000.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/mf2386","usgsCitation":"Linenkaemper, J.J., Dawson, T.E., Personius, S.F., Seitz, G., Reidy, L.M., and Schwartz, D.P., 2002, Logs and data from trenches across the Hayward Fault at Tyson's Lagoon (Tule Pond), Fremont, Alameda County, California: U.S. Geological Survey Miscellaneous Field Studies Map 2386, 2 Map Sheets: Sheet 1-45 x 30 inches, Sheet 2-33 x 44 inches; Pamphlet: 12 p., https://doi.org/10.3133/mf2386.","productDescription":"2 Map Sheets: Sheet 1-45 x 30 inches, Sheet 2-33 x 44 inches; Pamphlet: 12 p.","additionalOnlineFiles":"Y","costCenters":[{"id":648,"text":"Western Earthquake Hazards","active":false,"usgs":true}],"links":[{"id":182583,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9551,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2002/2386/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -123,37 ], [ -123,38 ], [ -122,38 ], [ -122,37 ], [ -123,37 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6ae4b07f02db63c69a","contributors":{"authors":[{"text":"Linenkaemper, James J.","contributorId":105797,"corporation":false,"usgs":true,"family":"Linenkaemper","given":"James","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":265681,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dawson, Timothy E.","contributorId":24429,"corporation":false,"usgs":false,"family":"Dawson","given":"Timothy","email":"","middleInitial":"E.","affiliations":[{"id":7099,"text":"Calif.

Bedrock strata include the Upper Cretaceous Mancos Shale through the Lower Jurassic Wingate Sandstone units. Below the Mancos Shale, which floors the Grand Valley, the Upper and Lower(?)Cretaceous Dakota Formation and the Lower Cretaceous Burro Canyon Formation hold up much of the resistant northeast- dipping monocline along the northeast side of the Uncompahgre uplift.  The impressive sequence of Jurassic strata below include the Brushy Basin, Salt Wash, and Tidwell Members of the Upper Jurassic Morrison Formation, the Middle Jurassic Wanakah Formation and informal 'board beds' unit and Slick Rock Member of the Entrada Formation, and the Lower Jurassic Kayenta Formation and Wingate Sandstone.  The Upper Triassic Chinle Formation and Early Proterozoic meta-igneous gneiss and migmatitic meta- sedimentary rocks, which are exposed in the Colorado National Monument quadrangle to the west, do not crop out here.  The monoclinal dip slope of the northeastern margin of the Uncompahgre uplift is apparently a Laramide structural feature.  Unlike the southwest-dipping, high-angle reverse faults in the Proterozoic basement and s-shaped fault- propagation folds in the overlying strata found in the Colorado National Monument 7.5' quadrangle along the front of the uplift to the west, the monocline in the map area is unbroken except at two localities.  One locality displays a small asymmetrical graben that drops strata to the southwest.  This faulted character of the structure dies out to the northwest into an asymmetric fault-propagation fold that also drops strata to the southwest.  Probably both parts of this structure are underlain by a northeast-dipping high-angle reverse fault.  The other locality displays a second similar asymmetric fold.  No evidence of post-Laramide tilting or uplift exists here, but the antecedent Unaweep Canyon, only 30 km to the south-southwest of the map area, provides clear evidence of Late Cenozoic, if not Pleistocene, uplift. The major geologic hazards in the area include large landslides associated with the dip-slope-underlain, smectite-rich Brushy Basin Member of the Morrison Formation and overlying Dakota and Burro Canyon Formations.  Active landslides affect the southern bank of the Colorado River where undercutting by the river and smectitic clays in the Mancos trigger landslides.  The Wanakah, Morrison, and Dakota Formations and the Mancos Shale create a significant hazard to houses and other structures by containing expansive smectitic clay.  In addition to seasonal spring floods associated with the Colorado and Gunnison Rivers, a serious flash flood hazard associated with sudden summer thunderstorms threatens the intermittent washes that drain the dip slope of the monocline.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf2363","usgsCitation":"Scott, R.B., Carrara, P.E., Hood, W.C., and Murray, K., 2002, Geologic map of the Grand Junction Quadrangle, Mesa County, Colorado: U.S. Geological Survey Miscellaneous Field Studies Map 2363, Map: 32.50 x 32.75 inches; Pamphlet: 20 p.; Companion Files; Metadata; Read Me, https://doi.org/10.3133/mf2363.","productDescription":"Map: 32.50 x 32.75 inches; Pamphlet: 20 p.; Companion Files; Metadata; Read Me","additionalOnlineFiles":"Y","costCenters":[],"links":[{"id":338299,"rank":11,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf-2363_pam.pdf","text":"Pamphlet"},{"id":338298,"rank":10,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf-2363_map_508.pdf","text":"Map - text only","size":"28 KB","linkFileType":{"id":1,"text":"pdf"}},{"id":110237,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_46652.htm","linkFileType":{"id":5,"text":"html"},"description":"46652"},{"id":182885,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf-2363_map.jpg"},{"id":338291,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf-2363.tar.gz","text":"GZIPPED TARRED archive of ArcInfo, metadata, etc.","size":"3.6 MB tar.gz"},{"id":338292,"rank":5,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf-2363base.tar.gz","text":"GZIPPED TARRED archive of base map","size":"10.7 MB tar.gz"},{"id":338293,"rank":6,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf2363.zip","text":"ZIPPED archive of ArcInfo, metadata, etc.","size":"3.4 MB","linkFileType":{"id":6,"text":"zip"}},{"id":338294,"rank":7,"type":{"id":16,"text":"Metadata"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf2363.met","text":"Metadata","size":"29 KB","linkFileType":{"id":2,"text":"txt"}},{"id":338295,"rank":8,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/gjtopo.zip","text":"ZIPPED archive of base map","size":"10.2 MB","linkFileType":{"id":6,"text":"zip"}},{"id":338296,"rank":8,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/README.TXT","text":"Read me","size":"1 KB","linkFileType":{"id":2,"text":"txt"}},{"id":338297,"rank":9,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/mf/2002/mf-2363/mf-2363_map.pdf","text":"Map","size":"3.9 MB","linkFileType":{"id":1,"text":"pdf"}}],"scale":"24000","country":"United States","state":"Colorado","county":"Mesa County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -108.61749999999999,39 ], [ -108.61749999999999,39.1175 ], [ -108.5,39.1175 ], [ -108.5,39 ], [ -108.61749999999999,39 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b01e4b07f02db6986dc","contributors":{"authors":[{"text":"Scott, Robert B. rbscott@usgs.gov","contributorId":766,"corporation":false,"usgs":true,"family":"Scott","given":"Robert","email":"rbscott@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":265720,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carrara, Paul E. pcarrara@usgs.gov","contributorId":1342,"corporation":false,"usgs":true,"family":"Carrara","given":"Paul","email":"pcarrara@usgs.gov","middleInitial":"E.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":265721,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hood, William C.","contributorId":100946,"corporation":false,"usgs":true,"family":"Hood","given":"William","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":265723,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Murray, Kyle E.","contributorId":31825,"corporation":false,"usgs":true,"family":"Murray","given":"Kyle E.","affiliations":[],"preferred":false,"id":265722,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The geologic map consists of new polygon (geologic map units) and line (contact, fault, fold axis, dike, flow contact, hachure) data, as well as point data (locations for structural measurements, geochemical and geochronologic data, geophysical soundings, and water wells).  The map database has been generated at 1:24,000 scale, and provides significant new geologic information for an area of the southern Cerros del Rio volcanic field, which sits astride the boundary of the Espanola and Santo Domingo basins of the Rio Grande rift.\r\n      The quadrangle includes the west part of the village of La Cienega along its eastern border and includes the southeasternmost part of the Cochiti Pueblo reservation along its northwest side.  The central part of the quadrangle consists of Santa Fe National Forest and Bureau of Land Management lands, and parts of several Spanish-era land grants.\r\n      Interstate 25 cuts through the southern half of the quadrangle between Santa Fe and Santo Domingo Pueblo.  Canada de Santa Fe, a major river tributary to the Rio Grande, cuts through the quadrangle, but there is no dirt or paved road along the canyon bottom.\r\n      A small abandoned uranium mine (the La Bajada mine) is found in the bottom of the Canada de Santa Fe about 3 km east of the La Bajada fault zone; it has been partially reclaimed.\r\n\r\n      The surface geology of the Tetilla Peak quadrangle consists predominantly of a thin (1-2 m generally, locally as thick as 10? m) layer of windblown surficial deposits that has been reworked colluvially.  Locally, landslide, fluvial, and pediment deposits are also important.  These colluvial deposits mantle the principal bedrocks units, which are (from most to least common):  (1) basalts, basanites, andesite, and trachyte of the Pliocene (2.7-2.2 Ma) Cerros del Rio volcanic field; (2) unconsolidated deposits of the Santa Fe Group, mainly along the western border, in the hanging wall of the La Bajada fault zone, but locally extending 2-3 km east under the Cerros del Rio volcanic field; (3) older Tertiary volcanic and sedimentary rocks (Abiquiu?, Espinaso, and Galisteo Formations); (4) intrusive rocks of the Cerrillos intrusive center that are roughly coeval with the Espinaso volcanic rocks; and (5) Mesozoic sedimentary rocks ranging in age from the Upper Triassic Chinle Formation to the Upper Cretaceous Mancos Shale.","language":"English","doi":"10.3133/mf2352","usgsCitation":"Sawyer, D., Shroba, R., Minor, S., and Thompson, R.A., 2002, Geologic map of the Tetilla Peak Quadrangle, Santa Fe and Sandoval counties, New Mexico: U.S. Geological Survey Miscellaneous Field Studies Map 2352, https://doi.org/10.3133/mf2352.","costCenters":[],"links":[{"id":182277,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":110236,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_46651.htm","linkFileType":{"id":5,"text":"html"},"description":"46651"},{"id":6037,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2002/mf-2352/","linkFileType":{"id":5,"text":"html"}}],"scale":"24000","country":"United States","state":"New Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -106.25,35.5 ], [ -106.25,35.6175 ], [ -106.11749999999999,35.6175 ], [ -106.11749999999999,35.5 ], [ -106.25,35.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db68a218","contributors":{"authors":[{"text":"Sawyer, D.A.","contributorId":107666,"corporation":false,"usgs":true,"family":"Sawyer","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":265708,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shroba, R.

Proterozoic metasedimentary and igneous rocks.  Tuffaceous rocks are found in fault-tilted blocks.  Only small outliers of the Dakota Sandstone, Morrison Formation, Entrada Sandstone, and Chinle Formation exist above the redbeds of the Permian-Pennsylvanian Maroon Formation and Pennsylvanian Minturn Formation, which were derived during erosion of the Ancestral Front Range east of the Gore fault zone.  In the southwestern area of the map, the proximal Minturn facies change to distal Eagle Valley Formation and the Eagle Valley Evaporite basin facies.  The Jacque Mountain Limestone Member, previously defined as the top of the Minturn Formation, cannot be traced to the facies change to the southwest.  Abundant surficial deposits include Pinedale and Bull Lake Tills, periglacial deposits, earth-flow deposits, common diamicton deposits, common Quaternary landslide deposits, and an extensive, possibly late Pliocene landslide deposit.  Landscaping has so extensively modified the land surface in the town of Vail that a modified land-surface unit was created to represent the surface unit.\r\n      Laramide movement renewed activity along the Gore fault zone, producing a series of northwest-trending open anticlines and synclines in Paleozoic and Mesozoic strata, parallel to the trend of the fault zone.  Tertiary down-to-the-northeast normal faults are evident and are parallel to similar faults in both the Gore Range and the Blue River valley to the northeast; presumably these are related to extensional deformation that occurred during formation of the northern end of the Rio Grande rift system in Colorado.\r\n      In the southwestern part of the map area, a diapiric(?) exposure of the Eagle Valley Evaporite exists and chaotic faults and folds suggest extensive dissolution and collapse of overlying bedrock, indicating the presence of a geologic hazard.  Quaternary landslides are common and indicate that landslide hazards are widespread in the area, particularly where old slide deposits are disturbed by construction.  The late Pliocene(?) landslide that consists largely of a smectitic upper Morrison Formation matrix and boulders of Dakota Sandstone is readily reactivated.  Debris flows are likely to invade low-standing areas within the towns of Vail and West Vail where tributaries of Gore Creek issue from the mountains on the north side of the valley.","language":"ENGLISH","doi":"10.3133/mf2369","usgsCitation":"Scott, R.B., Lidke, D.J., and Grunwald, D.J., 2002, Geologic map of the Vail West quadrangle, Eagle County, Colorado (Version 1.0): U.S. Geological Survey Miscellaneous Field Studies Map 2369, 18 p.; 1 map sheet 34 1/2 x 35 1/2 in.

The Iles Formation includes the Cozzette Sandstone and Corcoran Sandstone Members, which are undivided.  The Mancos Shale is divided into three members, an upper member, the Niobrara Member, and a lower member.  The Lower Cretaceous Dakota Sandstone, the Upper Jurassic Morrison Formation, and the Entrada Sandstone are present.  Below the Upper Jurassic Entrada Sandstone, the easternmost limit of the Lower Jurassic and Upper Triassic Glen Canyon Sandstone is recognized.  Both the Upper Triassic Chinle Formation and the Lower Triassic(?) and Permian State Bridge Formation are present.  The Pennsylvanian and Permian Maroon Formation is divided into two members, the Schoolhouse Member and a lower member.  All the exposures of the Middle Pennsylvanian Eagle Evaporite intruded into the Middle Pennsylvanian Eagle Valley Formation, which includes locally mappable limestone beds. The Middle and Lower Pennsylvanian Belden Formation and the Lower Mississippian Leadville Limestone are present.  The Upper Devonian Chaffee Group is divided into the Dyer Dolomite, which is broken into the Coffee Pot Member and the Broken Rib Member, and the Parting Formation.  Ordovician through Cambrian units are undivided.\r\n      The southwest flank of the White River uplift is a late Laramide structure that is represented by the steeply southwest-dipping Grand Hogback, which is only present in the southwestern corner of the map area, and less steeply southwest-dipping older strata that flatten to nearly horizontal attitudes in the northern part of the map area.  Between these two is a large-offset, mid-Tertiary(?) Rifle Falls normal fault, that dips southward placing Leadville Limestone adjacent to Eagle Valley and Maroon Formations.  Diapiric Eagle Valley Evaporite intruded close to the fault on the down-thrown side and presumably was injected into older strata on the upthrown block creating a blister-like, steeply north-dipping sequence of Mississippian and older strata.  Also, removal of evaporite by either flow or dissolution from under younger parts of the strata create structural benches, folds, and sink holes on either side of the normal fault.  A prominent dipslope of the Morrison-Dakota-Mancos part of the section forms large slide blocks that form distinctly different styles of compressive deformation called the Elk Park fold and fault complex at different parts of the toe of the slide.\r\n      The major geologic hazard in the area consist of large landslides both associated with dip-slope slide blocks and the steep slopes of the Eagle Valley Formation and Belden Formation in the northern part of the map.  Significant uranium and vanadium deposits were mined prior to 1980.","language":"English","doi":"10.3133/mf2341","usgsCitation":"Scott, R.B., Shroba, R.R., and Egger, A., 2001, Geologic map of the Rifle Falls quadrangle, Garfield County, Colorado: U.S. Geological Survey Miscellaneous Field Studies Map 2341, 1 map, https://doi.org/10.3133/mf2341.","productDescription":"1 map","costCenters":[],"links":[{"id":182682,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":110186,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_39197.htm","linkFileType":{"id":5,"text":"html"},"description":"39197"},{"id":6057,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2001/mf-2341/","linkFileType":{"id":5,"text":"html"}}],"scale":"24000","country":"United States","state":"Colorado","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -107.75,39.6175 ], [ -107.75,39.75 ], [ -107.61749999999999,39.75 ], [ -107.61749999999999,39.6175 ], [ -107.75,39.6175 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae2e4b07f02db688c59","contributors":{"authors":[{"text":"Scott, Robert B. rbscott@usgs.gov","contributorId":766,"corporation":false,"usgs":true,"family":"Scott","given":"Robert","email":"rbscott@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":265883,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shroba, Ralph R. 0000-0002-2664-1813 rshroba@usgs.gov","orcid":"https://orcid.org/0000-0002-2664-1813","contributorId":1266,"corporation":false,"usgs":true,"family":"Shroba","given":"Ralph","email":"rshroba@usgs.gov","middleInitial":"R.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":265884,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Egger, Anne","contributorId":100945,"corporation":false,"usgs":true,"family":"Egger","given":"Anne","affiliations":[],"preferred":false,"id":265885,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Alluvial deposits are mapped beneath flood plains, in stream terraces, and on hill slopes.  They include flood-plain and stream-channel alluvium, sheetwash alluvium, and undivided sheetwash alluvium and stream alluvium. Wind-deposited loess forms sheets that mantle inter-stream areas and late Wisconsin terrace alluvium. Peoria Loess is younger of the two loess sheets and covers much of the inter-stream area in the map area.  Loveland Loess is older and is exposed in a few small areas in the eastern part of the map area. Glacial deposits are chiefly heterogeneous, ice-deposited, clayey material (till) and minor interstratified stream-deposited sand and gravel.  Except for small outcrops, glacial deposits are covered by eolian and alluvial deposits throughout most of the map area.  Bedrock is locally exposed in natural exposures along the major streams and in quarries. It consists of Dakota Sandstone and chiefly limestone and shale of the Lansing and Kansas City Groups. Sand and gravel in flood plain and stream-channel alluvium in the Platte River valley are used mainly for concrete aggregate.
