This report contains field and laboratory data resulting from a trench study of the Hubbell Spring fault zone near Albuquerque, New Mexico. This trench was excavated in September, 1997, as part of earthquake hazards investigations of Quaternary faults in the Albuquerque metropolitan area. The trench was excavated across the youngest of several fault strands near the northern end of the Hubbell Spring fault zone. The site is located on Pueblo of Isleta tribal lands, approximately 1 km south of the southern boundary of Kirtland Air Force Base. Thus the paleoearthquake data derived from investigations at the Hubbell Spring site will be useful in assessing potential earthquake hazards in Isleta Pueblo, Kirtland Air Force Base/Sandia National Laboratories, and the Albuquerque metropolitan area. The purpose of this report is to present a detailed trench log, a scarp profile, soils data (table 1), magnetic susceptibility data (table 2), luminescence and uranium-series ages (tables 3 and 4), and detailed unit descriptions (table 5) obtained in this investigation. S.F. Personius had primary responsibility for siting, excavating, describing, and interpreting the trench; S.A. Mahan did the luminescence dating, and James B. Paces did the uranium-series dating. M.C. Eppes and D.W. Love assisted with trench logging and mapping; and M.C. Eppes, D.K. Mitchell, and A. Murphy did the soils analyses.

The map is part of a cooperative U.S. Geological Survey and National Park Service project to provide geologic information for areas within the newly established Grand Canyon/Parashant Canyon National Monument. Most of the Grand Canyon and parts of the adjacent plateaus have been geologically mapped; this map fills in one of the remaining areas where uniform quality geologic mapping was needed. The geologic information presented may be useful in future related studies as to land use management, range management, and flood control programs for federal and state agencies, and private concerns. The map area is in a remote region of the Arizona Strip, northwestern Arizona about 88 km south of the nearest settlement of St. George, Utah. Elevations range from about 1,097 m (3,600 ft) in Parashant Canyon (south edge of map area) to 2,145 m (7,037 ft) near the east-central edge of the map area. Primary vehicle access is by dirt road locally known as the Mount Trumbull road; unimproved dirt roads and jeep trails traverse various parts of the map area. Travel on the Mount Trumbull road is possible with 2-wheel-drive vehicles except during wet conditions. Extra fuel, two spare tires and extra food and water are highly recommended when traveling in this remote area. The map area includes about 26 sections of land belonging to the State of Arizona, about 40 sections of private land, and a small strip of the Lake Mead National Recreation Area (southeast edge of the map area). The private land is mainly clustered around the abandoned settlement of Mt. Trumbull, locally known as Bundyville, and a few sections are scattered in the upper Whitmore Canyon area just south of Bundyville. Lower elevations within the canyons support a sparse growth of sagebrush, cactus, grass, creosote bush, and a variety of desert shrubs. Sagebrush, grass, cactus, cliffrose bush, pinyon pine trees, juniper trees, and some ponderosa pines thrive at higher elevations. Surface runoff in the north half of the map area drains northward towards the Virgin River in Utah via Hurricane Wash. In the south half of the area, it drains towards the Colorado River in Grand Canyon via Parashant and Whitmore Canyons. Upper Parashant and Whitmore Canyons are part of the physiography of the western Grand Canyon, but are not included within Grand Canyon National Park. The entire map area is now within the newly established Grand Canyon/Parashant Canyon National Monument (as of January, 2000), and is jointly managed by the Lake Mead National Recreational Area, Boulder City, Nevada, and the Bureau of Land Management, Arizona Strip District, St. George, Utah.

Shallow earth slides and debris flows were the most common, but a few deep-seated rotational earth slides also occurred. The landslides caused significant property damage and interfered with rail traffic; future landslides in the area pose significant hazards to property and public safety. Field observations indicate that ground-water seepage, runoff concentration, and dumping at the tops of the bluffs all contributed to instability of the bluffs. Most landslides in the study area occurred in colluvium, residuum, and landslide deposits derived from the Vashon Drift, particularly the advance outwash. In the northern part of the area, colluvium derived from the Pleistocene Whidbey Formation was also involved in shallow landslides. Comparison of recent activity with historic records in the southern part of the map area indicates that landslides tend to occur in many of the same areas as previous landslides.

Elsewhere in the study area, younger rocks conceal the San Rafael Group. The Morrison Formation is also generally well exposed throughout the area. From near Monticello to Harts Draw, Cretaceous rocks conceal the Morrison Formation. In the study area, two unconformities are associated with the rocks described herein. One at the base of the San Rafael Group (termed J-2) at the contact with the Lower Jurassic Navajo Sandstone and the other at the top (J-5) at the contact with the overlying Morrison Formation. The J-5 unconformity is the datum used to construct the line of graphic sections and the restored stratigraphic diagram of this report.

The map database represents the integration of previously published reports and new geologic mapping and field checking by the author (see Sources of Data index map on the map sheet or the Arc-Info coverage pi-so and the textfile pi-so.txt). The descriptive text (below) contains new ideas about the Hayward fault and other faults in the East Bay fault system, as well as new ideas about the geologic units and their relations.\r\n\r\nThese new data are released in digital form in conjunction with the Federal Emergency Management Agency Project Impact in Oakland. The goal of Project Impact is to use geologic information in land-use and emergency services planning to reduce the losses occurring during earthquakes, landslides, and other hazardous geologic events. The USGS, California Division of Mines and Geology, FEMA, California Office of Emergency Services, and City of Oakland participated in the cooperative project.\r\n\r\nThe geologic data in this report were provided in pre-release form to other Project Impact scientists, and served as one of the basic data layers for the analysis of hazard related to earthquake shaking, liquifaction, earthquake induced landsliding, and rainfall induced landsliding.\r\n\r\nThe publication of these data provides an opportunity for regional planners, local, state, and federal agencies, teachers, consultants, and others outside Project Impact who are interested in geologic data to have the new data long before a traditional paper map could be published. Because the database contains information about both the bedrock and surficial deposits, it has practical applications in the study of groundwater and engineering of hillside materials, as well as the study of geologic hazards and the academic research on the geologic history and development of the region.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/mf2342","usgsCitation":"Graymer, R., 2000, Geologic Map and Map Database of the Oakland Metropolitan Area, Alameda, Contra Costa, and San Francisco Counties, California (Online Version 1.0): U.S. Geological Survey Miscellaneous Field Studies Map 2342, Packages; Individual Files (Pamphlet: 31 p., Map: 35 x 49 inches); Database Files, https://doi.org/10.3133/mf2342.","productDescription":"Packages; Individual Files (Pamphlet: 31 p., Map: 35 x 49 inches); Database Files","additionalOnlineFiles":"Y","costCenters":[{"id":647,"text":"Western Earth Surface Processes","active":false,"usgs":true}],"links":[{"id":110100,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_29220.htm","linkFileType":{"id":5,"text":"html"},"description":"29220"},{"id":183657,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9533,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2000/2342/","linkFileType":{"id":5,"text":"html"}}],"scale":"50000","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.36749999999999,37.6175 ], [ -122.36749999999999,38 ], [ -122,38 ], [ -122,37.6175 ], [ -122.36749999999999,37.6175 ] ] ] } } ] }","edition":"Online Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ae223","contributors":{"authors":[{"text":"Graymer, R.

Because the map area is dominated by various surficial deposits, the map depicts 22 different Quaternary units. Two prominent river terraces are present in the quadrangle containing gravels deposited by the Colorado River. The map area contains many mass movement deposits. Extensive landslide deposits are present along the eastern part of the quadrangle. These massive landslides originate on the flanks of Grand Mesa, in the Green River and Wasatch Formations, and flow west onto the Palisade quadrangle. In addition, large areas of the eastern and southern parts of the map are covered by extensive pediment surfaces. These pediment surfaces are underlain by debris flow deposits also originating from Grand Mesa. Material in these deposits consists of mainly subangular basalt cobbles and boulders and indicate that these debris flow deposits have traveled as much as 10 km from their source area. The pediment surfaces have been divided into 5 age classes based on their height above surrounding drainages. Two common bedrock units in the map area are the Mancos Shale and the Mesaverde Group both of Upper Cretaceous age. The Mancos shale is common in low lying areas near the western map border. The Mesaverde Group forms prominent sandstone cliffs in the north-central map area. The map is accompanied by a separate pamphlet containing unit descriptions, a section on geologic hazards (including landslides, piping, gullying, expansive soils, and flooding), and a section on economic geology (including sand and gravel, and coal). A table indicates what map units are susceptible to a given hazard. Approximately twenty references are cited at the end of the report.","language":"ENGLISH","doi":"10.3133/mf2326","usgsCitation":"Carrara, P.E., 2000, Geologic map of the Palisade quadrangle, Mesa County, Colorado: U.S. Geological Survey Miscellaneous Field Studies Map 2326, 1 map, https://doi.org/10.3133/mf2326.","productDescription":"1 map","costCenters":[],"links":[{"id":184464,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":110070,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25789.htm","linkFileType":{"id":5,"text":"html"},"description":"25789"},{"id":6019,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2000/mf-2326/","linkFileType":{"id":5,"text":"html"}}],"scale":"24000","country":"United States","state":"Colorado","county":"Mesa","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adee4b07f02db6874b9","contributors":{"authors":[{"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":261376,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":69291,"text":"mf2336 - 2000 - Geology of the Cape MendocinoGeology of the Cape Mendocino, Eureka, Garberville, and southwestern part of the Hayfork 30 x 60 minute quadrangles and adjacent offshore area, northern California, with digital database","interactions":[],"lastModifiedDate":"2022-06-28T20:49:52.820426","indexId":"mf2336","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2336","title":"Geology of the Cape MendocinoGeology of the Cape Mendocino, Eureka, Garberville, and southwestern part of the Hayfork 30 x 60 minute quadrangles and adjacent offshore area, northern California, with digital database","docAbstract":"Introduction\r\n\r\nThese geologic maps and accompanying structure sections depict the geology and structure of much of northwestern California and the adjacent continental margin. The map area includes the Mendocino triple junction, which is the juncture of the North American continental plate with two plates of the Pacific ocean basin. The map area also encompasses major geographic and geologic provinces of northwestern California. The maps incorporate much previously unpublished geologic mapping done between 1980 and 1995, as well as published mapping done between about 1950 and 1978. To construct structure sections to mid-crustal depths, we integrate the surface geology with interpretations of crustal structure based on seismicity, gravity and aeromagnetic data, offshore structure, and seismic reflection and refraction data.\r\n\r\nIn addition to describing major geologic and structural features of northwestern California, the geologic maps have the potential to address a number of societally relevant issues, including hazards from earthquakes, landslides, and floods and problems related to timber harvest, wildlife habitat, and changing land use. All of these topics will continue to be of interest in the region, as changing land uses and population density interact with natural conditions. In these interactions, it is critical that the policies and practices affecting man and the environment integrate an adequate understanding of the geology.\r\n\r\nThis digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area.

Reports of landsliding began in early January 1998 and continued throughout the winter and spring. On February 9, President Clinton declared all 10 counties eligible for Federal Emergency Management Agency (FEMA) disaster assistance. In April and May of 1998, personnel from the U.S. Geological Survey (USGS) conducted a field reconnaissance in the area to provide a general overview of landslide damage resulting from the 1997-98 sequence of El Nino-related storms. Seven scientists from the USGS Landslide Hazards Program based in Reston, Virginia; Golden, Colorado; and Menlo Park, California; and five scientists from the USGS Geologic Mapping Program?s San Francisco Bay Mapping Team based in Menlo Park, California, cooperated in the landslide-damage assessments. \r\n\r\nThe assessments were done for 10 counties in the Bay area: Alameda, Contra Costa, Marin, Napa, San Francisco, Santa Clara, Santa Cruz, San Mateo, Solano, and Sonoma. \r\nUSGS Maps in this series include: MF-2325-A (Napa County), MF-2325-B (Alameda County), MF-2325-C (Marin County), MF-2325-D (Santa Cruz County), MF-2325-E (Contra Costa County), MF-2325-F (Sonoma County), MF-2325-G (San Francisco City and County), MF-2325-H (San Mateo County), MF-2325-I (Solano County), MF-2325-J (Santa Clara County). In addition to USGS scientists providing data from the field evaluation, each of the counties, many consultants, and others cooperated fully in providing the landslide-damage information compiled here.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/mf2325","collaboration":"Pamphlet to accompany Miscellaneous Field Studies Maps MF-2325-A-J","usgsCitation":"Godt, J.W., 1999, Maps Showing Locations of Damaging Landslides Caused by El Nino Rainstorms, Winter Season 1997-98, San Francisco Bay Region, California: U.S. Geological Survey Miscellaneous Field Studies Map 2325, Available online, https://doi.org/10.3133/mf2325.","productDescription":"Available online","numberOfPages":"4","onlineOnly":"Y","additionalOnlineFiles":"Y","temporalStart":"1997-11-01","temporalEnd":"1998-04-30","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true},{"id":363,"text":"Landslide Hazards Program","active":false,"usgs":true}],"links":[{"id":195669,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":7947,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/1999/mf-2325/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64acbb","contributors":{"authors":[{"text":"Godt, Jonathan W. 0000-0002-8737-2493 jgodt@usgs.gov","orcid":"https://orcid.org/0000-0002-8737-2493","contributorId":1166,"corporation":false,"usgs":true,"family":"Godt","given":"Jonathan","email":"jgodt@usgs.gov","middleInitial":"W.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true},{"id":508,"text":"Office of the AD Hazards","active":true,"usgs":true}],"preferred":true,"id":287930,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":61375,"text":"mf2325G - 1999 - Map showing locations of damaging landslides in San Francisco City and County, California, resulting from 1997-98 El Nino rainstorms","interactions":[{"subject":{"id":61375,"text":"mf2325G - 1999 - Map showing locations of damaging landslides in San Francisco City and County, California, resulting from 1997-98 El Nino rainstorms","indexId":"mf2325G","publicationYear":"1999","noYear":false,"chapter":"G","title":"Map showing locations of damaging landslides in San Francisco City and County, California, resulting from 1997-98 El Nino rainstorms"},"predicate":"IS_PART_OF","object":{"id":76804,"text":"mf2325 - 1999 - Maps Showing Locations of Damaging Landslides Caused by El Nino Rainstorms, Winter Season 1997-98, San Francisco Bay Region, California","indexId":"mf2325","publicationYear":"1999","noYear":false,"title":"Maps Showing Locations of Damaging Landslides Caused by El Nino Rainstorms, Winter Season 1997-98, San Francisco Bay Region, California"},"id":1}],"isPartOf":{"id":76804,"text":"mf2325 - 1999 - Maps Showing Locations of Damaging Landslides Caused by El Nino Rainstorms, Winter Season 1997-98, San Francisco Bay Region, California","indexId":"mf2325","publicationYear":"1999","noYear":false,"title":"Maps Showing Locations of Damaging Landslides Caused by El Nino Rainstorms, Winter Season 1997-98, San Francisco Bay Region, California"},"lastModifiedDate":"2022-09-26T20:56:54.565952","indexId":"mf2325G","displayToPublicDate":"2002-02-01T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2325","chapter":"G","title":"Map showing locations of damaging landslides in San Francisco City and County, California, resulting from 1997-98 El Nino rainstorms","docAbstract":"Heavy rainfall associated with a strong El Nino caused over $150 million in landslide damage in the 10-county San Francisco Bay region during the winter and spring of 1998.

Sedimentologic, geomorphic, and chronologic evidence at sites shown on the map indicates that Lakes Lahontan and Columbus-Rennie were as much as 70 m higher in the early-middle Pleistocene than during their late Pleistocene high stands. Lake Lahontan at its 1400-m shoreline level would submerge present-day Reno, Carson City, and Battle Mountain, and would flood other now-dry basins. To the east, Lakes Jonathan (new name), Diamond, Newark, and Hubbs also reached high stands during the early-middle(?) Pleistocene that were 25-40 m above their late Pleistocene shorelines; at these very high levels, the lakes became temporarily or permanently tributary to the Humboldt River and hence to Lake Lahontan. Such a temporary connection could have permitted fish to migrate from the Humboldt River southward into the presently isolated Newark Valley and from Lake Lahontan into Fairview Valley. The timing of drainage integration also provides suggested maximum ages for fish to populate the basins of Lake Diamond and Lake Jonathan. Reconstructing and dating these lake levels also has important implications for paleoclimate, tectonics, and drainage evolution in the western Great Basin. For example, shorelines in several basins form a stair-step sequence downward with time from the highest levels, thought to have formed at about 650 ka, to the lowest, formed during the late Pleistocene. This descending sequence indicates progressive drying of pluvial periods, possibly caused by uplift of the Sierra Nevada and other western ranges relative to the western Great Basin. However, these effects cannot account for the extremely high lake levels during the early middle Pleistocene; rather, these high levels were probably due to a combination of increased effective moisture and changes in the size of the Lahontan drainage basin.","language":"ENGLISH","doi":"10.3133/mf2323","usgsCitation":"Reheis, M., 1999, Extent of Pleistocene lakes in the western Great Basin (Version 1.0): U.S. Geological Survey Miscellaneous Field Studies Map 2323, 1 map :col. ;82 x 78 cm., on sheet 111 x 95 cm., https://doi.org/10.3133/mf2323.","productDescription":"1 map :col. ;82 x 78 cm., on sheet 111 x 95 cm.","costCenters":[],"links":[{"id":109883,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_22945.htm","linkFileType":{"id":5,"text":"html"},"description":"22945"},{"id":182825,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":6026,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/1999/mf-2323/","linkFileType":{"id":5,"text":"html"}}],"scale":"800000","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121,37 ], [ -121,43 ], [ -114,43 ], [ -114,37 ], [ -121,37 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49b8e4b07f02db5cd781","contributors":{"authors":[{"text":"Reheis, Marith C. 0000-0002-8359-323X","orcid":"https://orcid.org/0000-0002-8359-323X","contributorId":101244,"corporation":false,"usgs":true,"family":"Reheis","given":"Marith C.","affiliations":[],"preferred":false,"id":264204,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":61376,"text":"mf2325I - 1999 - Map showing locations of damaging landslides in Solano County, California, resulting from 1997-98 El Nino rainstorms","interactions":[],"lastModifiedDate":"2012-02-10T00:10:42","indexId":"mf2325I","displayToPublicDate":"2002-02-01T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2325","chapter":"I","title":"Map showing locations of damaging landslides in Solano County, California, resulting from 1997-98 El Nino rainstorms","docAbstract":"Heavy rainfall associated with a strong El Nino caused over $150 million in landslide damage in the 10-county San Francisco Bay region during the winter and spring of 1998.
