Total relief is nearly 1,200 ft, ranging from a low elevation of 1,640 ft along the southwestern edge of the area, to a high point of about 2,860 ft in the northwest portion. Principal access is provided by state Route 100 and 155 on the southeast and northeast, and by Forest Service Road 10 along the western boundary. Old logging roads and foot trails allow entry to the interior of the study area. Several swamps and one small pond are located in topographically low areas. Drainage is principally to the south and southeast by tributaries of the south-flowing West River, ultimately discharging into the Connecticut River near Brattleboro.</p>\n<p>The Devils Den area is named for a large undercut cliff (Dale, 1915, p. 21) developed in Precambrian basement rocks. This undercut cliff forms a broad natural cave immediately west of and below Forest Service Road 10, at the head of Mt. Tabor Brook. Another much smaller cave is present in dolomite of probable Paleozoic (Early Cambrian) age on the east side of the same road. This smaller cave apparently is of artificial origin, having been made during early mining of the dolomite (Dale, 1915, p. 21).

This report presents results of geochemical studies carried out in June and July, 1982, as part of the investigation of the Buffalo Peaks Wilderness Study Area, Colo. Stream-sediment and panned-concentrate samples were collected from about 80 sites on streams draining the study area. Analytical results and a sample locality map were published by Domenico and others (1984).</p>\n<p>The geologic and mineral resource potential maps of the study area were prepared by Hedlund and others (1983). The Buffalo Peaks Wilderness Study Area encompasses a major portion of the Mosquito Range, which is structurally part of the east flank of the north-northwest-trending Sawatch anticline. Bedrock in the west two-thirds of the study area is made up of Precambrian igneous and metamorphic rocks of the core of the anticline, whereas bedrock in the east one-third is mostly east dipping Paleozoic sedimentary rocks. In the vicinity of East and West Buffalo Peaks, the sequence of Paleozoic sedimentary rocks is covered by Tertiary extrusive rocks.</p>\n<p>Major faults generally run parallel to the north-northwest trend of the Arkansas River Valley, which is an expression of the Arkansas River segment of the Rio Grande depression, and the Sawatch anticline in the study area. Some faults are probably of late Precambrian age; major recurrent displacement is known to have occurred on most faults during Laramide time and in the Pliocene and Miocene.</p>\n<p>The study area is bounded by several areas of known mineralization (Hedl und and others, 1983). Vein and bedding replacement deposits of silver, zinc, and lead were mined from 1890 until about 1918 in the vicinity of Weston Pass (map A), on the northeastern border of the study area. Gold and silver were mined from about 1860 until about 1880 from veins in the Granite area (map A), on the northwestern border of the study area; minor prospecting activity continues today.

To the west, the range slopes steeply from the crest then more gently along the lower flanks to the Werde River, one of the main drainage channels of Arizona. In the northern part of the wilderness, the East Werde River, a tributary of the Verde, occupies a deep canyon that separates the Mazatzal Mountains from mesas to the north. The lowest parts of the wilderness have altitudes of about 2,200 ft and are located near Bartlett Reservoir in the southwestern part of the area studied.</p>\n<p>Two aeromagnetic surveys were flown and interpreted to aid in the delineation of subsurface lithology and structure: one survey was flown at a low level (1,000 ft above ground) and the other at a high level (9,000 ft above sea level).

This report and map represent only the results of the aeromagnetic compilation from previous publications (U.S. geological Survey, 1975a,b,c). The wilderness encompasses 61 mi<sup>2</sup> (37,232 acres) within the Cibola National Forest, but the map area is about 145 mi<sup>2</sup> and includes areas adjacent to the wilderness boundary.</p>\n<p>The Sandia Mountains are a part of an eastward-tilted fault block that is about 18 mi long and 8-10 mi wide and that is continuous with the Manzanita-Manzano Mountain fault blocks to the south of Tijeras Canyon (fig. 1). The westward-facing Sandia range front of Precambrian crystalline rocks is capped by about 2,500 ft of Pennsylvanian and Permian limestone, sandstone, and siltstone strata that dip 15&deg;-20&deg; eastward to form the dip slope of the tilted fault block.</p>\n<p>About 40-50 percent of the rocks exposed in the Sandia Mountains are of Precambrian age and include an older group of greenstone, metarhyolite, quartzite, and gneiss that is intruded by the Sandia Granite (1,445 m.y.). Paleozoic strata, about 2,500 ft thick, comprise about 30 percent of the outcrop area and form an extensive dip slope on the tilted fault block.

These faults have as much as 20,000-28,000 ft of throw. Numerous north-trending faults along the dip slope are considered coeval with the range-front faults and have had an important influence on the localization of barite-fluorite veins.

As part of that work, multichannel reflection surveys were started in 1979 in the Charleston area, on 1 and (Behrendt and others, 1981; Hamilton and others, 1983) and offshore (Behrendt and others, 1983). The data for lines across the continental margin were tied into the USGS offshore seismic grid in the area discussed by Dillon and others (1979). At about the same time (1978&ndash;79), Consortium for Continental Reflection Profiling (COCORP) lines in Georgia and in the Charleston, S. C., area were recorded (Cook and others, 1979; Cook and others, 1981; Schilt and others, 1983). The COCORP data for Georgia (Cook and others, 1979) and other reflection data to the northeast, as discussed by Harris and Bayer (1979), indicated the presence of the Appalachian d&eacute;collement, extending seaward from the Appalachian Mountains. The authors of these papers inferred that the Appalachian d&eacute;collement might extend across the Piedmont and Coastal Plain to the continental shelf. Subsequently, Iverson and Smithson (1982) suggested, on the basis of their reprocessing of the COCORP line in Georgia, that the d&eacute;collement was rooted in the area of the Kings Mountain and the Carolina slate belts.</p>\n<p>The multichannel seismic-reflection data for the Charleston, S. C., area (Behrendt and others, 1981, 1983; Schilt and others, 1983) provided evidence, particularly strong offshore, of the existence of a reflecting surface at a depth of 11.4&plusmn;1.5 km that was suggested as a d&eacute;collement. Behrendt and others (1981, 1983) suggested that the Charleston earthquake of 1886 might have been caused by movement on the d&eacute;collement or on associated listric faults. Seeber and Armbruster (1981) suggested that movement on the Appalachian d&eacute;collement, if it continued coastward to Charleston, might have caused the Charleston earthquake of 1886. The best determined focal depths for recent seismicity, from data recorded by a seismograph network operated by the USGS in the Charleston, S. C., area since 1973, are shallower than 13+2 km (Tarr and others, 1981; and Tarr and Rhea, 1983), or above the suggested d&eacute;collement.</p>\n<p>The seismic-reflection data have also shown the existence of several Triassic (?) basins beneath the Coastal Plain Late Cretaceous and Cenozoic sedimentary rock section (Behrendt and others, 1981; Behrendt, 1983; Costain and Glover, 1983; Hamilton and others, 1983; Petersen and others, 1984). The basins, in several cases, appear to be bounded by high-angle normal faults. Some of these faults may have been reactivated in Late Cretaceous and Cenozoic time as apparently reverse faults. Also they are suggested to be listric onto the d&eacute;collement, thereby bearing a causal relation to Charleston seismicity (Behrendt, 1983; Behrendt and others, 1983).</p>\n<p>The question of whether the Appalachian d&eacute;collement is continuous to the coast is, therefore, important not only for the general understanding of the tectonics of the southeastern United States but for an understanding of the earthquake-hazard question as well. For these reasons, three long, deep-crustal, multichannel seismic-reflection profiles (S4, S6, and S8) were obtained by the USGS to address the problem. This report presents illustrations of interpretations of the profiles discussed by Behrendt (in press).</p>\n<p>The Appalachian d&eacute;collement does not appear continuous from the Appalachian Mountains to the coast but rather appears to extend southeastward only to the Carolina slate belt. A series of reflections on lines S4, S6, and S8 and on the COCORP line is interpreted as evidence of southeastward-dipping imbricate faults, from the Brevard fault on the northwest to beyond the Augusta fault, which marks the southeastern extent of the Eastern Piedmont fault zone. The Carolina slate belt is characterized on the four seismic profiles by a complex series of diffractions and reflections extending from less than 1 s to 8 s. These arrivals are possibly the result of layering in the metasedimentary rocks complexly disrupted by the imbricate faults. A number of Triassic (?) basins are apparent in the reflection data for the rifted Charleston terrane identified from low-gradient magnetic anomalies.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf1656","isbn":"0607814918","collaboration":"Prepared in cooperation with the U.S. Nuclear Regulatory Commission","usgsCitation":"Behrendt, J.C., 1985, Interpretations from multichannel seismic-reflection profiles of the deep crust crossing South Carolina and Georgia from the Appalachian Mountains to the Atlantic Coast: U.S. Geological Survey Miscellaneous Field Studies Map 1656, 3 Plates: 57.80 x 37.89 inches or smaller, https://doi.org/10.3133/mf1656.","productDescription":"3 Plates: 57.80 x 37.89 inches or smaller","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":326351,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf1656.JPG"},{"id":327137,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1656/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":327136,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1656/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":327138,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1656/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"9000","country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -84.5,31.333333333333332 ], [ -84.5,35 ], [ -80,35 ], [ -80,31.333333333333332 ], [ -84.5,31.333333333333332 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d9e4b07f02db5dff43","contributors":{"authors":[{"text":"Behrendt, John C. jbehrendt@usgs.gov","contributorId":25945,"corporation":false,"usgs":true,"family":"Behrendt","given":"John","email":"jbehrendt@usgs.gov","middleInitial":"C.","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true},{"id":213,"text":"Crustal Imaging and Characterization Team","active":false,"usgs":true}],"preferred":false,"id":261105,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

An intensive study of the water and sediments in the vicinity of the treatment plant was conducted in 1979-80 in order to characterize the major factors controlling the mobility of effluent-derived phosphorus in the area. \r\n\r\nThe transport of phosphorus near the treatment plant was found to be affected by the circulation regime, by inorganic adsorption reactions with sediments, and by metabolic uptake and release by phytoplankton. The effect of river discharge on the convective transport of phosphorus near the outfall is significantly reduced by a mid-river shoal area, which confines the flow path of the effluent to an embayment on the eastern side of the river for a distance of 4 kilometers below the outfall. This embayment appears to serve as a sediment trap, where protection from bottom scour during high-flow events has permitted fine-grained sediments to accumulate. Measurements of mean residence time indicate that the effluent leaves the embayment area 21? days after being discharged from the outfall. \r\n\r\nMeasurements of the linear decay constant for the removal of dissolved phosphorus from the water column reveal a diurnal cycle corresponding to the metabolic utilization of phosphorus by phytoplankton. This cyclic removal is superimposed on a constant and noncyclic adsorption of phosphorus by inorganic phases. Forty-eight hour average values of the linear decay constant for dissolved phosphorus in the area range from 0.4 to 1.1 per day. \r\n\r\nAnalyses of bottom sediments indicate that approximately 13 percent of the phosphorus discharged between September 1977 and August 1980 has been retained in the embayment. The primary inorganic phase responsible for phosphorus adsorption is amorphous iron (ferric oxy-hydroxides); amorphous aluminum and clay minerals appear to play secondary roles. The accumulation of sorbed phosphorus in the embayment has been promoted by the deposition of fine-grained sediments enriched in ferric oxy-hydroxides. Conversely, the absence of ferric oxy-hydroxides in coarse-grained sediments near the outfall has facilitated the precipitation of the ferrous phosphate mineral vivianite.","language":"English","publisher":"U.S. General Printing Office","doi":"10.3133/wsp2231","usgsCitation":"Hearn, 1985, Controls on phosphorus mobility in the Potomac River near the Blue Plains wastewater treatment plant: U.S. Geological Survey Water Supply Paper 2231, v, 46 p., https://doi.org/10.3133/wsp2231.","productDescription":"v, 46 p.","costCenters":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"links":[{"id":137053,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2231/report-thumb.jpg"},{"id":27015,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2231/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"District of Columbia, Maryland, Virginia","otherGeospatial":"Potomac River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -77.07149505615234,\n              38.810419613702024\n            ],\n            [\n              -77.00042724609374,\n              38.810419613702024\n            ],\n            [\n              -77.00042724609374,\n              38.89383860542579\n            ],\n            [\n              -77.07149505615234,\n              38.89383860542579\n            ],\n            [\n              -77.07149505615234,\n              38.810419613702024\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adae4b07f02db6856e1","contributors":{"authors":[{"text":"Hearn, Jr. phearn@usgs.gov","contributorId":1950,"corporation":false,"usgs":true,"family":"Hearn","suffix":"Jr.","email":"phearn@usgs.gov","affiliations":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"preferred":false,"id":144206,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

I n 1980, the area had a population of more than 1.1 million, or about 77 percent of Utah's total population. It contains several large cities, including Salt Lake City, Ogden, and Provo, and is commonly called Utah's urban corridor.</p><p>Most of the water supply for the Wasatch Front area comes from streams that originate in the Wasatch Range and nearby Uinta Mountains; however, ground water has played an important role in the economic growth of the area. The principal source of ground water is the unconsolidated fill (sedimentary deposits) in the valleys of the Wasatch Front area northern Juab, Utah, Goshen, and Salt Lake Valleys; the East Shore area (a valley area east of the Great Salt Lake), and the Bear River Bay area. Maximum saturated thickness of the fill in the principal ground-water reservoirs in these valleys exceeds 6,000 feet, and the estimated volume of water that can be withdrawn from just the upper 100 feet of the saturated fill is about 8 million acre-feet. In most places the water is fresh, containing less than 1,000 milligrams per liter of dissolved solids; in much of the Bear River Bay area and most of Goshen Valley (and locally in the other valleys), the water is slightly to moderately saline, with 1,000 to 10,000 milligrams per liter of dissolved solids.</p><p>The principal ground-water reservoirs receive recharge at an annual rate that is estimated to exceed 1 million acre-feet chiefly as seepage from consolidated rocks in the adjacent mountains from canals, ditches, and irrigated land, directly from precipitation, and from streams. Discharge during 1980 (which was chiefly from springs, seepage to streams, evapotranspiration, and withdrawal by wells) was estimated to be about 1.1 million acre-feet. Withdrawal from wells, which began within a few years after the arrival of the Mormon pioneers in the Salt Lake Valley in 1847, and had increased to about 320,000 acre-feet during 1979. Additional withdrawals from wells may cause water levels to decline, possibly leading to such problems as conflicts among water-right owners, increased pumping costs, land subsidence, and deterioration of ground-water quality. Some of these problems cannot be avoided if the principal ground-water reservoirs are to be fully used; however, management practices such as artificial ground-water recharge in intensivelypumped areas may help to alleviate those problems. </p>","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/wsp2232","usgsCitation":"Price, D., 1985, Ground water in Utah's densely populated Wasatch Front area - The challenge and the choices: U.S. Geological Survey Water Supply Paper 2232, vii, 71 p., https://doi.org/10.3133/wsp2232.","productDescription":"vii, 71 p.","costCenters":[{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true}],"links":[{"id":139112,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2232/report-thumb.jpg"},{"id":28758,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2232/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Utah","otherGeospatial":"Wasatch Front","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab0e4b07f02db66dacb","contributors":{"authors":[{"text":"Price, Don","contributorId":30608,"corporation":false,"usgs":true,"family":"Price","given":"Don","email":"","affiliations":[],"preferred":false,"id":145356,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
