Quaternary geology of the Nenana River and adjacent parts of the Alaska Range, Alaska
Clyde Wahrhaftig
1953, Open-File Report 53-262
The Nenana River flows northward across the Alaska Range near 149° west longitude. Sedimentary bedrock formations of its basin include pre-Cambrian schist undifferentiated Paleozoic and Mesozoic rocks, continental upper Cretaceous rocks and poorly consolidated continental Tertiary rocks. Igneous rocks include pre Devonian quartz orthoclase schist, greenstone, granitic and basic intrusives...
Stratigraphic sections at White Pine copper mine, Ontonagon County, Michigan
Walter S. White, J.C. Wright
1953, Open-File Report 53-269
The lithology and stratigraphy of the ore zones near the base of the Nonesuch formation in the vicinity of the White Pine copper mine, Ontonagon County, Michigan, are shown on preliminary stratigraphic sections that have been made available for examination.Partial logs of 91 holes, drilled by the Copper Range Company...
Geology and coal deposits of Jarvis Creek coalfield, Alaska
Clyde Wahrhaftig, C.A. Hickcox
1953, Open-File Report 53-263
The Jarvis Creek coal field lies on the north side of the Alaska Range between latitudes 63°35' and 63°45 N., and longitudes 145°40' and 145°50 W. It is 2 to 6 miles east of the Richardson Highway. The coal field is about 16 square miles in area, the major part...
Stratigraphic sections of the Phosphoria formation measured and sampled in 1952
Thomas McGiffin Cheney, R.P. Sheldon, E. R. Cressman, R.A. Smart, L.D. Carswell
1953, Open-File Report 53-36
A series of reports presenting detailed stratigraphic sections and analyses of samples of the Phosphoria formation in the western phosphate field is being prepared for publication as U. S. Geological Survey Circulars. To speed the availability of these data to industry and others having immediate need for such basic information,...
Potential industrial sites in the Lynn Canal area, Alaska
Arthur Johnson, William Stephens Twenhofel
1953, Circular 280
Full development of a proposal to divert the headwaters of the Yukon River drainage from Canada into the Taiya River valley of Alaska would make available more than a half million kilowatts of electrical energy. Utilization of this block of power, for which there is at present no local market,...
Sedimentation in small reservoirs on the San Rafael Swell, Utah
Norman Julius King, Mervyn M. Mace
1953, Circular 256
Movement of sediment from upland areas and eventually into main drainages and rivers is by no means through continuous transportation of material from the source to the delta. Instead it consists of a series of intermittent erosional and depositional phases that present a pulsating movement. Hence, sediment carried off upland...
Geology and pegmatites of part of the Fourmile area, Custer County, South Dakota
Andrew J. Lang, Jack Allison Redden
1953, Circular 245
The Fourmile area, Custer County, S. Dak., is underlain by pre-Cambrian metamorphic rocks that surround the granitic core of the Black Hills. The main structure in the area is the upright limb of an overturned anticline that plunges about 30 ? S. 10 ? E. Three units of metamorphic rocks...
Water-power resources of Crystal River, Colorado
Fred Forrest Lawrence
1953, Circular 292
The Crystal River drains the western slope of the Elk Mountains, a relatively small range in the southern Rocky Mountain province, and flows into the Roaring Fork 13 miles southeast of Glenwood Springs, Colo. The lower 7 miles of the valley is cultivated, but upstream from this stretch the valley...
