Geology and ground-water resources of Clayton County, Iowa
W. L. Steinhilber, O. J. Van Eck, A.J. Feulner
1961, Water Supply Bulletin 7
Clayton County includes 784 square miles in northeastern Iowa and in 1960 had a population of 21, 962.  For the most part, the county is a dissected upland that is drained mainly by the southeastward flowing Turkey River and its principal tributary, the Volga River.  The Turkey River empties into...
Philosophy for water development
Luna Bergere Leopold, E. L. Hendricks
1961, Conference Paper
There is probably no one in this room who has not had an experience analogous to the one I here describe. You sat at the dinner table next to a nice lady who impressed you with her breadth of interest in community affairs. She said to you "Oh, you work...
The trout fishery in Shenandoah National Park
Robert E. Lennon
1961, Special Scientific Report - Fisheries 395
Populations of brook trout in streams of Shenandoah National Park were reduced drastically early in the past decade by a succession of unusually severe droughts and floods. The drying of stream beds, predation, and scouring were principal factors in the loss of fish. The park was closed to fishing in...
Preliminary geologic report on the 1960 U.S. Expedition to bellingshausen sea, Antarctica
C. Craddock, H.A. Hubbard
1961, Science (133) 886-887
Thurston Peninsula, although largely snow covered, exposes massive to foliated dioritic rock and schist exhibiting northeast-trending structures. One basalt pebble was found. The adjacent continental shelf is cut by submarine valleys. Peter I Island, a dissected basaltic volcano 250 miles to the northeast, was visited....
Dating desert ground water
L. Thatcher, M. Rubin, Glen F. Brown
1961, Science (134) 105-106
Tritium in Arabian rainfall has followed the trend observed in North America with peaks in 1958 and the spring of 1959. These measurements will be useful for future hydrologie studies. Water from wadi gravels averages 10 yr old. Carbon-14 measurements of deep waters indicate ages of several thousand years....
Detrital-appearing uraninite grains in the shinarump member of the chinle formation in northern Arizona
R.G. Petersen
1960, Economic Geology (55) 138-149
A sample of uranium-bearing conglomerate from the Shinarump member of the Chinle formation in northern Arizona was disaggregated in an ultrasonic separator. The sample, weighing 187 grams, contained about 60 grains of uraninite (from 0.1 to 1 mm diameter) which have the sphericity and polish suggestive of detrital grains. The detrital-appearing grains are associated with abundant...
Ground-water areas and well logs, central Sevier Valley, Utah
Richard A. Young
1960, Utah State Engineer Information Bulletin 3
Between September 1959 and June 1960 the United States Geological Survey and the Utah State Engineer, with financial assistance from Garfield, Millard, Piute, Sanpete, and Sevier Counties and from local water-users’ associations, cooperated in an investigation to determine the structural framework of the central Sevier Valley and to evaluate the...
Ground-water investigations in Utah in 1960 and ground-water reports published by the U.S. Geological Survey or the Utah State Engineer prior to 1960
Harry D. Goode
1960, Utah State Engineer Information Bulletin 4
Listed below and shown on the map are projects in the ground-water program being conducted cooperatively by the U.S. Geological Survey and the Utah State Engineer. Project UT-5 is conducted from a field office in Cedar City, project UT-17 from a field office in Richfield, project UT-26 from a field...
A statistical analysis of the distribution of a larval nematode (Anisakis sp.) in the musculature of chum salmon (Oncorhynchus keta - Walbaum)
A.J. Novotny
1960, Experimental Parasitology (10) 60-67
The pepsin-HCl digestion technique is probably the best method of isolating Anisakislarvae from the musculature of chum salmon. Some losses can be expected due to breakage of the resistant cuticle of Anisakis, and can be estimated to be about 6% when counting the parasites with the unaided eye. Comparisons of Anisakis infections of the dorsal...
A bacterial disease of yellow perch (Peres flavescens)
A. J. Ross, P.R. Nordstrom, J.E. Bailey, J.H. Heaton
1960, Transactions of the American Fisheries Society (89) 310-312
On May 26, 1959, two of the authors' investigated a fish kill at Dailey Lake, Park County, Montana. They observed about a half-dozen live, weakly swimming yellow perch (Perca flavescens), in addition to thousand of dead perch along the shoreline. It was learned from local residents that mortalities had begun...
Ovarian fluid: Its role in fertilization
R.R. Rucker, J.F. Conrad, C.W. Dick
1960, Progressive Fish-Culturist (22) 77-78
FISH-CULTURISTs, in general, do not agree as to the time of actual fertilization of artificially spawned salmonid eggs. Some fish-culturists believe that the eggs are fertilized in the milt before water is added, while others are equally certain that fertilization is not achieved until after water is added. This difference...
