This map is one of a series of three reconnaissance geologic maps of the southern Misheguk Mountain quadrangle (fig. 1). Because the geology in all three map areas is similar, a composite map explanation has been designed to facilitate their combined use and provide the reader with a better perspective of the regional geology. There are some rock units and allochthons which do not occur on all three maps. For this reason, the explanation contains more rock units than occur on any one map. Rock units which appear on the accompanying map are indicated by an asterisk beside the map symbol in the explanation.

A sharp contrast in temperature gradient at ~600 m represents a contrast in thermal conductivity caused by the downward change from interstitial ice to interstitial water at the base of permafrost under near steady-state conditions. Interpretation of the gradient contrast in terms of a simple model for the conductivity of an aggregate yields the mean ice content and thermal conductivities for the frozen and thawed sections (8.1 and 4.7 mcal/cm sec ?C, respectively). These results yield a heat flow of ~1.3 HFU which is similar to other values on the Alaskan Arctic Coast; the anomalously deep permafrost is a result of the anomalously high conductivity of the siliceous ice-rich sediments. Curvature in the upper 160 m of the temperature profiles represents a warming of ~1.8?C of the mean surface temperature, and a net accumulation of 5-6 kcal/cm 2 by the solid earth surface during the last 100 years or so. Rising sea level and thawing sea cliffs probably caused the shoreline to advance tens of kilometers in the last 20,000 years, inundating a portion of the continental shelf that is presently the target of intensive oil exploration. A simple conduction model suggests that this recently inundated region is underlain by near-melting ice-rich permafrost to depths of 300-500 m; its presence is important to seismic interpretations in oil exploration and to engineering considerations in oil production. With confirmation of the permafrost configuration by offshore drilling, heat-conduction models can yield reliable new information on the chronology of arctic shorelines.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82535","usgsCitation":"Lachenbruch, A., Sass, J., Marshall, B., and Moses, T.H., 1982, Thermal regime of permafrost at Prudhoe Bay, Alaska: U.S. Geological Survey Open-File Report 82-535, 77 p. :ill., map ;28 cm., https://doi.org/10.3133/ofr82535.","productDescription":"77 p. :ill., map ;28 cm.","costCenters":[],"links":[{"id":140718,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0535/report-thumb.jpg"},{"id":35038,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0535/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a08e4b07f02db5fa30a","contributors":{"authors":[{"text":"Lachenbruch, A.H.","contributorId":76737,"corporation":false,"usgs":true,"family":"Lachenbruch","given":"A.H.","affiliations":[],"preferred":false,"id":156198,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sass, J.H.","contributorId":70749,"corporation":false,"usgs":true,"family":"Sass","given":"J.H.","email":"","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":156196,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Marshall, B.V.","contributorId":72375,"corporation":false,"usgs":true,"family":"Marshall","given":"B.V.","affiliations":[],"preferred":false,"id":156197,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moses, T.

This map is one of a series of three reconnaissance geologic maps of the southern Misheguk Mountain quadrangle (fig. 1). Because the geology in all three map areas is similar, a composite map explanation has been designed to facilitate their combined use and provide the reader with a better perspective of the regional geology. There are some rock units and allochthons which do not occur on all three maps. For this reason, the explanation contains more rock units than occur on any one map. Rock units which appear on the accompanying map are indicated by an asterisk beside the map symbol in the explanation.

It ranges in thickness from 2600 m in the Atigun River area to 700 m south of Anaktuvuk Pass and has been subdivided into four regionally persistent members: (a) the basal sandstone member, consisting of marine sandstone and shale with some conglomerate; (b) the lower shale member, consisting of nonmarine quartzite, conglomerate and shale; (c) the middle conglomerate member, consisting of nonmarine pebble and cobble conglomerate and quartzite; and (d) the Stuver Member, consisting of nonmarine sandstone and shale. The Kanayut conformably overlies the Upper Devonian marine Hunt Fork Shale and is conformably overlain by the Mississippian marine Kayak Shale. The Kanayut is wholly allochthonous and has probably been transported northward on a series of thrust plates. \r\n\r\nThe basal sandstone member of the Kanayut Conglomerate, which overlies prodelta turbidites of the Hunt Fork Shale, contains marginal-marine coarsening-upward channel-mouth bar sequences. It is conformably overlain by the lower shale member. \r\n\r\nMeasured sections of the nonmarine members of the Kanayut show that the lower shale member ranges in thickness from 120 m to 1115 m and consists of fining-upward cycles interpreted to have been deposited by meandering streams on a broad floodplain. These cycles contain, in ascending order, channelized basal conglomerate, trough cross-stratified sandstone, and ripple-marked siltstone. The cycles are interpreted to be channel and point-bar deposits. Individual cycles average about 10 m in thickness and are separated by intervals of black, brown or maroon floodplain shale deposits. These typically contain thin coarsening-upward units that probably represent prograding levee sequences and irregular and ungraded sandstone bodies interpreted to be crevasse-splay deposits. In the Okokmilaga River area, the lower shale member contains a distinctive coarse-grained unit which is burrowed and interpreted to represent a widespread marine incursion. \r\n\r\nThe middle conglomerate member, which ranges in thickness from 155 m to 525 m, consists of braidplain deposits. It contains fining-upward couplets of conglomerate and parallel-stratified or cross-stratified sandstone that average 2-7 m in thickness. The couplets record deposition in channels and on bars of braided streams. The middle conglomerate member contains the largest clasts, little or no shale, and represents the maximum progradation of nonmarine sedimentation in the Kanayut depositional system. \r\n\r\nThe Stuver Member consists of fining-upward cycles that resemble those of the lower shale member. It ranges in thickness from 160 m to 1400 m and grades upward into tidal and marginal-marine deposits of the Kayak Shale. \r\n\r\nConglomerate in the Kanayut is compositionally very mature, averaging 82 percent white, gray, black or red chert clasts, 14 percent vein quartz clasts, 3 percent quartzite clasts, and less than I percent other lithologies, mainly argillite. Although red chert is locally abundant in the Shainin Lake-Galbraith Lake area, there is little variation in conglomerate composition in the Kanayut, suggesting derivation from a single major source terrane.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr82199","usgsCitation":"Nilsen, T.H., Moore, T., Balin, D.F., and Johnson, S.Y., 1982, Sedimentology and stratigraphy of the Kanayut Conglomerate, central Brooks Range, Alaska: Report of 1980 field season: U.S. Geological Survey Open-File Report 82-199, iv, 81 p., https://doi.org/10.3133/ofr82199.","productDescription":"iv, 81 p.","costCenters":[],"links":[{"id":410493,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_75624.htm","linkFileType":{"id":5,"text":"html"}},{"id":34953,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0199/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":140441,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0199/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"central Brooks Range","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -154.4667,\n 67.8333\n ],\n [\n -148.5,\n 67.8333\n ],\n [\n -148.5,\n 68.45\n ],\n [\n -154.4667,\n 68.45\n ],\n [\n -154.4667,\n 67.8333\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dfe4b07f02db5e3c15","contributors":{"authors":[{"text":"Nilsen, T.

Monitoring two such craters in the Beaufort Sea, we found that in relatively unprotected sites they fill in by deposition from bedload in 2 to 3 years. Net westward sediment transport results in sand layers dipping at the angle of repose westward into the strudel-scour crater, whereas the west wall of the crater remains steep to vertical. Initially the crater traps almost all bedload: sand, pebbles, and organic detritus; as infilling progresses, the materials are increasingly winnowed, and bypassing must occur. Over a 20-m-wide sector, an exposed strudel scour trapped 360 m3 of bedload during two seasons; this infilling represents a bedload transport rate of 9 m3 yr^-1 m^-1. This rate should be applicable to a 4.5-km-wide zone with equal exposure and similar or shallower depth. Within this zone, the transport rate is 40,500 m3 yr^-1, similar to estimated longshore transport rates on local barrier beaches. On the basis of the established rate of cut and fill, all the delta-front deposits should consist of strudel-scour fill. Vibracores typically show dipping interbedded sand and lenses of organic material draped over very steep erosional contacts, and an absence of horizontal continuity of strata--criteria that should uniquely identify high-latitude deltaic deposits. Given a 2- to 3-year lifespan, most strudel scours seen in surveys must be old. The same holds true for ice gouges and other depressions not adjusted to summer waves and currents, although these features record events of only the past few years. In view of such high rates of bottom reworking of the shallow shelf, any human activities creating turbidity, such as dredging, would have little effect on the environment. However, huge amounts of transitory material trapped by long causeways planned for offshore development would result in major changes in the environment.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82588","usgsCitation":"Reimnitz, E., and Kempema, E., 1982, High rates of bedload transport measured from infilling rate of large strudelscour craters in the Beaufort Sea, Alaska: U.S. Geological Survey Open-File Report 82-588, 19 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr82588.","productDescription":"19 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":145562,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0588/report-thumb.jpg"},{"id":38629,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0588/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db6359f7","contributors":{"authors":[{"text":"Reimnitz, Erk","contributorId":17963,"corporation":false,"usgs":true,"family":"Reimnitz","given":"Erk","email":"","affiliations":[],"preferred":false,"id":162038,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kempema, E.

Mineral deposits in the study area have been mined or prospected intermittently since about 1900, and production of small tonnages of ores containing gold, silver, copper, lead, zinc, and tungsten has been recorded. Extensive exploration and development currently (1981) is underway at a molybdenum prospect about 65 km east of Ketchikan. Our mineral-resource assessment indicates that the area contains potentially significant amounts of those metallic commodities, as well as of molybdenum, iron, antimony, and barite. The results of these studies have been published in a folio of maps accompanied by descriptive texts, diagrams, tables, and pertinent references. The present report serves as a guide to these investigations, provides relevant background information, and integrates the component maps and reports. It also describes revisions to the geology based on studies completed since the folio was published and includes a list of specific and general references on the geology and mineral deposits of the study area.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/cir855","usgsCitation":"Berg, H., 1982, The Alaska Mineral Resource Assessment Program: Guide to information about the geology and mineral resources of the Ketchikan and Prince Rupert quadrangles, southeastern Alaska: U.S. Geological Survey Circular 855, iii, 24 p., https://doi.org/10.3133/cir855.","productDescription":"iii, 24 p.","costCenters":[],"links":[{"id":391884,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_23951.htm"},{"id":139234,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1982/0855/report-thumb.jpg"},{"id":31265,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1982/0855/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alaska","otherGeospatial":"Ketchikan and Prince Rupert quadrangles","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -132,\n 54.717\n ],\n [\n -130,\n 54.717\n ],\n [\n -130,\n 56\n ],\n [\n -132,\n 56\n ],\n [\n -132,\n 54.717\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db6835c1","contributors":{"authors":[{"text":"Berg, Henry C.","contributorId":73176,"corporation":false,"usgs":true,"family":"Berg","given":"Henry C.","affiliations":[],"preferred":false,"id":148308,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":7087,"text":"ofr821039 - 1982 - Depth and temperature of permafrost on the Alaskan Arctic Slope; preliminary results","interactions":[],"lastModifiedDate":"2012-02-02T00:06:07","indexId":"ofr821039","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"82-1039","title":"Depth and temperature of permafrost on the Alaskan Arctic Slope; preliminary results","docAbstract":"As permafrost is defined by its temperature, the only way to determine its depth is to monitor the return to equilibrium of temperatures in boreholes that penetrate permafrost. Such measurements are under way in 25 wells on the Alaskan Arctic Slope; 21 are in Naval Petroleum Reserve Alaska (NPRA), and 4 are in the foothills to the east. Near-equilibrium results indicate that permafrost thickness in NPRA generally ranges between 200 and 400 m (compared to 600+ m at Prudhoe Bay); there are large local variations and no conspicuous regional trends. By contrast the long-term mean temperature of the ground surface (one factor determining permafrost depth) varies systematically from north to south in a pattern modified by the regional topography. The observed variation in permafrost temperature and depth cannot result primarily from effects of surface bodies of water or regional variations in heat flow; they are consistent, however, with expectable variations in the thermal conductivity of the sediments. It remains to be determined (with conductivity measurements) whether certain sites with anomalously high local gradients have anomalously high heat flow; if they do, they might indicate upwelling of interstitial fluids in the underlying basin sediments.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr821039","usgsCitation":"Lachenbruch, A.H., Sass, J., Lawver, L., Brewer, M., and Moses, T., 1982, Depth and temperature of permafrost on the Alaskan Arctic Slope; preliminary results: U.S. Geological Survey Open-File Report 82-1039, 30 p. :ill., map ;28 cm., https://doi.org/10.3133/ofr821039.","productDescription":"30 p. :ill., map ;28 cm.","costCenters":[],"links":[{"id":141344,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/1039/report-thumb.jpg"},{"id":34414,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/1039/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa8e4b07f02db667a77","contributors":{"authors":[{"text":"Lachenbruch, Arthur H.","contributorId":27850,"corporation":false,"usgs":true,"family":"Lachenbruch","given":"Arthur","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":154243,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sass, J.H.","contributorId":70749,"corporation":false,"usgs":true,"family":"Sass","given":"J.H.","email":"","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":154245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lawver, L.A.","contributorId":73599,"corporation":false,"usgs":true,"family":"Lawver","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":154246,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brewer, M.C.","contributorId":54994,"corporation":false,"usgs":true,"family":"Brewer","given":"M.C.","email":"","affiliations":[],"preferred":false,"id":154244,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Moses, T.H.","contributorId":24344,"corporation":false,"usgs":true,"family":"Moses","given":"T.H.","email":"","affiliations":[],"preferred":false,"id":154242,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":32564,"text":"pp1216A - 1982 - A Late Devonian (Frasnian) microbiota from the Farewell-Lyman Hills area, west-central Alaska","interactions":[],"lastModifiedDate":"2022-02-10T21:01:21.235225","indexId":"pp1216A","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":331,"text":"Professional Paper","code":"PP","onlineIssn":"2330-7102","printIssn":"1044-9612","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"1216","chapter":"A","title":"A Late Devonian (Frasnian) microbiota from the Farewell-Lyman Hills area, west-central Alaska","docAbstract":"

During the 1980 summer season, approximately 1600 km of multisensored, high-resolution geophysical profile data were collected along a rectangular grid with 4.8 km line spacing. Interpretation of these data is presented on five maps showing bathymetry, sea-floor microrelief, ice-gouge characteristics, Holocene sediment thickness, and geologic structure to depths of approximately 1000 m. \r\n\r\nOn a broad scale, the seafloor is shallow and almost flat, although microrelief features produced by sediment transport and ice-gouge processes typically vary up to several meters in amplitude. Microrelief bedforms related to hydraulic processes are predominant in water depths less than 12 m. Microrelief caused by ice gouging generally increases with water depth, reaching a maximum of 2 m or more in water depths beyond the 20 m isobath. This intensely gouged area lies beneath the shear zone between the seasonal landfast ice and the mobile polar ice pack. \r\n\r\nThe thickness of recent (Holocene) sediment increases offshore, from 2 m near the Colville River delta to 30 m or more on the outer shelf. The thin Holocene layer is underlain by a complex horizon interpreted to be the upper surface of a Pleistocene deposit similar in composition to the present Arctic Coastal Plain. The base of the inferred Pleistocene section is interpreted to be a low-angle unconformity 100 m below sea level. Beneath this Tertiary-Quaternary unconformity, strata are interpreted to be alluvial fan-delta plain deposits corresponding to the Colville Group and younger formations of Late Cretaceous to Tertiary age. Numerous high-angle faults downthrown to the north trend across the survey area. With few exceptions, these faults terminate at or below the 100 m unconformity, suggesting that most tectonism occurred before Quaternary time. Acoustic anomalies suggesting gas accumulation are rare, and where identified typically occur adjacent to faults. A laterally continuous zone of poor seismic data occurs in the nearshore area and is interpreted to be caused by subsea permafrost. This report describes these geologic conditions in Harrison Bay and discusses potential hazards that they may pose for future oil and gas operations in Sale 71 and adjacent Beaufort Sea shelf areas.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr8235","usgsCitation":"Craig, J., and Thrasher, G.P., 1982, Environmental geology of Harrison Bay, northern Alaska: U.S. Geological Survey Open-File Report 82-35, iii, 28 p., 6 over-size sheets, ill., maps ;28 cm., https://doi.org/10.3133/ofr8235.","productDescription":"iii, 28 p., 6 over-size sheets, ill., maps ;28 cm.","costCenters":[],"links":[{"id":140504,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0035/report-thumb.jpg"},{"id":36009,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0035/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36010,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0035/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36011,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0035/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36012,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0035/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36013,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0035/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36014,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0035/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36015,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0035/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db6723d7","contributors":{"authors":[{"text":"Craig, J.D.","contributorId":14405,"corporation":false,"usgs":true,"family":"Craig","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":157726,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thrasher, G.
