The bedrock was mapped and samples collected during the summers of 1969, 1970, and 1971 as part of a continuing&nbsp;U.S. Geological Survey project to map basement rocks in the western Chugach Mountains.</p>\n<p>Most of the early work on the bedrock geology of the Anchorage A-6 quadrangle was done by Capps (1916 and 1940), who studied the geology of the Turnagain-Knik region, and by Park (1933), who studied the Girdwood gold mining district, most of which is in the Anchorage A-6 quadrangle. Recent studies of bedrock in the quadrangle and nearby areas are described in papers by Clark and Bartsch&nbsp;(1971a, b) and Clark (in press, a, b).</p>\n<p>Grateful acknowledgement is given to several persons who made valuable contributions to this report. They include Henry R. Schmoll and Ernest Dobrovolny who mapped the contacts between bedrock and surficial deposits shown in figure 1, David L. Jones who did the paleontological studies, and Susan R.

Resulting movement of ground water through the thaw bulb might produce quick conditions in the pipeline foundation materials. A digital model showed that such conditions are not likely to occur. Test drilling along the proposed route of the pipeline confirms this conclusion. An exception may be the situation in which the pipeline is buried in fine sand overlying a highly permeable coarse sand or gravel.</p><p>The results of model studies demonstrate that the heated trench will focus ground-water discharge near the pipeline, especially in winter. Such discharge will increase the number and size of icings.</p><p>Explosive icing mounds apparently result from high crystallization pressures that develop within a closed talik. The thaw bulb close to the buried pipeline relieves the pressure that leads to such conditions.</p><p>Potential problems related to thaw-bulb enlargement by heat convection and thaw-instability of fine-grained materials are not treated in this analysis.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr72349","usgsCitation":"Sloan, C.E., and Bredehoeft, J.D.,

One of the major hazards to the proposed pipeline and its associated roads and facilities is flooding. Floods could inundate or erode foundations of structures, could cause pipeline rupture resulting in oil spillage, or could increase erosion especially where natural floodways have been altered by clearing, excavation, and other construction activities. The primary damage to the environment from accelerated flood erosion could be the degradation of water quality and its detrimental effects on fish and other organisms. Consequently, information on floods along the pipeline corridor is vitally needed to assess possible environmental damages and to aid in the design and management of the pipeline and associated facilities. This report presents a description of existing flood information and a description of flood surveys at 13 sites along the northern segment of the proposed TAPS route from Prudhoe Bay to the Salcha River. A similar report is planned for the southern segment of the TAPS route.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr7345","usgsCitation":"Childers, J.M., 1972,

The two main units in this belt are the Jurassic (?) and Cretaceous Valdez (?) Group composed of flysch deposits and the McHugh Complex composed of oceanic metavolcanic sequences tectonically mixed with metaclastic rocks derived from a continental magmatic arc. Deformation of the McHugh Complex is characterized by pervasive, closely spaced shear fractures and is melange-like in some areas. Deformation of the Valdez (?) Group is characterized by tight folding that was initiated before the sediments were completely lithified. The folds have steeply dipping axial surfaces that are overturned to the northwest in some areas and to the southeast in other areas. The Jurassic and(or) Cretaceous McHugh Complex is separated from the Valdez (?) Group by the Eagle River thrust fault. The Valdez (?) Group was probably deposited primarily on oceanic crust that was collapsed against the continental margin in latest Cretaceous to early Tertiary time.&nbsp;</p><p>An accurate belt of upper Paleozoic to lower Mesozoic rocks to the north and west had been deformed, accreted to the continental margin, and intruded by plutons prior to the deposition of the Jurassic (?) and Cretaceous sediments. Rocks of the continental terrane that underlie the Wrangell and Talkeetna Mountains and the Alaska Range are locally exposed in the map area north and west of the Knik fault zone. Near the village of Eklutna, the junction between the two terranes is marked by an ophiolitic assemblage.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/mf350","usgsCitation":"Clark, S.H., 1972, Reconnaissance bedrock geologic map of the Chugach Mountains near Anchorage, Alaska: U.S. Geological Survey Miscellaneous Field Studies Map 350, 1 Plate: 36.85 x 25.10 inches, https://doi.org/10.3133/mf350.","productDescription":"1 Plate: 36.85 x 25.10 inches","costCenters":[],"links":[{"id":180250,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/mf/0350/report-thumb.jpg"},{"id":418018,"rank":2,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/0350/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"250000","country":"United States","state":"Alaska","city":"Anchorage","otherGeospatial":"Chugach Mountains","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -150,60.75 ], [ -150,61.5 ], [ -148.75,61.5 ], [ -148.75,60.75 ], [ -150,60.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a74e4b07f02db6447a1","contributors":{"authors":[{"text":"Clark, Sandra H.
