Wendell V. Tangborn, Lawrence R. Mayo, David R. Scully, Robert M. Krimmel
1977, Professional Paper 715-B
Combined ice and water balances were measured in the 1967 hydrologic year (October 1-September 30) on four glaciers in western North America ranging in latitude from 37 deg to 63 deg N. This hydrologic year was characterized by heavier than normal winter precipitation in California and Washington and abnormally dry...

Bathymetric and shoreline changes, northwestern Prudhoe Bay, Alaska
Peter W. Barnes, Erk Reimnitz, Greg Smith, John Melchior
1977, Open-File Report 77-161
The coastal environment in the vicinity of Prudhoe Bay, Alaska (Fig. 1) is presently being vigorously utilized by petroleum activities. In particular, barges moving freight onshore over the past 8 years, have used the Prudhoe Bay entrance channel almost exclusively. To further facilitate the offloading of supply barges, Atlantic Richfield...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: April 1977
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1977, Open-File Report 77-300-D
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Ground-water investigation at the alluvial fan of the South Fork River, Anchorage, Alaska: results of test drilling, 1976
Larry L. Dearborn
1977, Open-File Report 77-493
In late 1976, at Anchorage, Alaska, a ground-water exploration well was drilled to a depth of 487 feet on the South Fork Eagle River fan near the confluence with the mainstream. The well penetrated four sand and gravel strata of low water-yielding capacity and extended 37 ft into metamorphic bedrock....

Epithermal beryllium deposits in water-laid tuff, western Utah
David A. Lindsey
1977, Economic Geology (72) 219-232
Epithermal beryllium deposits in western Utah have distinctive geological and geochemical associations that provide guides to exploration for new resources of beryllium and associated metals. Beryllium deposits at Spor Mountain and the Honeycomb Hills are uniquely associated with topaz-bearing rhyolite of Late Tertiary age and are restricted to porous water-laid...
Spectacular mobility of ash flows around Aniakchak and Fisher calderas, Alaska
T. P. Miller, R.L. Smith
1977, Geology (5) 173-176
Ash flows around Aniakchak and Fisher calderas in the Aleutian volcanic arc show evidence of having flowed over formidable topographic barriers at distances of tens of kilometres from their source. Ash flows swept down glaciated valleys on the south side of Aniakchak caldera, crossed a broad lowland with an altitude...
Tertiary and Quaternary deposits at The Palisades, central Alaska
Warren E. Yeend
1977, Journal of Research of the U.S. Geological Survey (5) 747-752
The Palisades of the Yukon River, located near the geographic center of Alaska, has long been an attraction to people traveling along the river. Numerous scientific field parties have viewed or visited the locality and published short accounts of their observations. The river bluffs are as much as 90 meters...
Spherulitic rhyolite dike from Goat Island, southeastern Alaska
Walter R. Vennum, G. Donald Eberlein
1977, Journal of Research of the U.S. Geological Survey (5) 445-451
Spherulites, as much as 4 mm in diameter, locally constitute almost 50 percent by volume of a dark-red rhyolite dike that intrudes porphyritic pyroxene gabbro along the northeast coast of Goat Island, 3.2 km northwest of Hydaburg, southeastern Alaska. The largest spherulites are composed mainly of o-quartz, whereas the smallest...
Benthic invertebrates in an arctic mountain stream, Brooks Range, Alaska
K. V. Slack, J.W. Nauman, L. J. Tilley
1977, Journal of Research of the U.S. Geological Survey (5) 519-527
A 1-day, late-summer reconnaissance of the Dietrich River, Alaska, determined species composition and diversity of benthic invertebrates and examined the correlation between stream order and invertebrate distribution. Benthic invertebrates were collected by dip net, drift net, and 10-rock collections, and results were combined for each station. Forty-nine taxa were identified...
A reconnaissance investigation of a large meromictic lake in southeastern Alaska
George A. McCoy
1977, Journal of Research of the U.S. Geological Survey (5) 319-324
Redoubt Lake is one of the largest documented meromictic lakes in North America. The chemocline extends in depth from 80 to 100 m (meters) and the steepest gradient is between 98 and 100 m. The monimolimnion is anoxic, contains hydrogen sulflde, and has a salinity about two-thirds that of seawater....
Metamorphic rocks of the Yakutat-St. Elias area, south-central Alaska
Travis Hudson, George Plafker, Donald L. Turner
1977, Journal of Research of the U.S. Geological Survey (5) 173-184
Metamorphic rocks in the Yakutat-St. Elias area range in grade from zeolite to amphibolite facies. Radiometric age determinations on selected metamorphic rocks have helped to identify two major metamorphic events, one in Late Cretaceous time that was characterized by penetrative deformation, and one in the Miocene Epoch that resulted in...
Intrusive rocks of the Yakutat-St. Elias area, south-central Alaska
Travis Hudson, George Plafker, Marvin A. Lanphere
1977, Journal of Research of the U.S. Geological Survey (5) 155-172
Twenty-three plutons, exposed over a total area of nearly 1200 km2, have been studied in the Alaska part of the St. Elias Mountains between long 138° and 141°W. Results of potassium-argon age determinations combined with field relations, petrography, and major- and trace-element chemistry suggest six major intrusive events: (1) late...
Sheeted dikes, gabbro, and pillow basalt in flysch of coastal southern Alaska
Russell G. Tysdal, J.E. Case, G. R. Winkler, S. H. B. Clark
1977, Geology (5) 377-383
A Paleocene to Eocene(?) mafic sequence of igneous rocks on Knight Island and a Cretaceous mafic and ultramafic sequence of the Resurrection Peninsula in coastal southern Alaska are characterized by pillow basalts, sheeted dikes, and gabbro intrusions. At both localities, pillow basalts are interbedded with flysch, and the gabbros intrude...
