War on lampreys
James W. Moffett
1953, Philadelphia Enquirer, 23 August 1953 16-17
Vampire-like sea lampreys look somewhat like short sections of garden hose, swim like eels, and live solely on the blood of fishes. Their voracious appetites have been especially harmful to fish in the Great Lakes, and it is there that methods of underwater electrocution are being applied in their...
The effect of ether anesthesia on fin-clipping rate
Paul H. Eschmeyer
1953, Progressive Fish-Culturist (15) 80-82
As part of an experimental program to learn the effects of stocking lake trout (Salvelinus namaycush) in Lake Superior, 141, 392 fingerlings were marked at the Charlevoix (Michigan) Station of the U.S. Fish and Wildlife Service in October 1952. The adipose fin was removed from all fish, the right pelvic...
Lake fisheries need lamprey control and research
James W. Moffett
1953, The Fisherman (21) 10-11
Since 1921, when the first sea lamprey was recorded from Lake Erie, concern about this parasite in the Great Lakes above Niagara Falls, where previously it had never occurred, grew successively. At first, the concern was shared only in scientific circles, but as the parasite continued its persistent and...
Lake Bonneville: Geology of northern Utah Valley, Utah
C. B. Hunt, H.D. Varnes, H. E. Thomas
1953, Professional Paper 257-A
Lake Bonneville was a vast Pleistocene lake that covered 20,000 square miles in northwestern Utah and had a maximum depth of about 1,000 feet. It was a body of water comparable in size to modern Lake Michigan.Surveys of the unconsolidated deposits in the Lake Bonneville basin utilize the same methods...
Relation of suspended-sediment concentration to channel scour and fill
Luna Bergere Leopold, Thomas Maddock Jr.
1953, Conference Paper, Proceedings of the fifth Hydraulics Conference, June 9-11, 1952, arranged by the Iowa Institute of Hydraulic Research
It is known that during the passage of a flood the channel of an alluvial stream scours and fills with considerable rapidity. Though such changes may be random, it seems more likely that there is a definite pattern of channel change directly related both to discharge and to the sediment...
Ground-water conditions in artesian aquifers in Brown County, Wisconsin
William James Drescher
1953, Water Supply Paper 1190
The principal water-bearing rocks underlying Brown County, Wis., are thick sandstone units of Cambrian and Ordovician age. Other aquifers include limestone and dolomite of Ordovician age, dolomite of Silurian age, and sands and gravel of Pleistocene and Recent age. Underlying the water-bearing formations are crystalline rocks of pre-Cambrian age which...
Fluctuations in the fisheries of State of Michigan waters of Green Bay
Ralph Hile, George F. Lunger, Howard J. Buettner
1953, Fishery Bulletin of the U.S. Fish and Wildlife Service (54) 1-34
Green Bay, traditionally a major center of production, has assumed in recent years a position of overwhelming dominance in the commercial fisheries of the State of Michigan waters of Lake Michigan. Within the 4-year period 1945-1948 the commercial take in State of Michigan waters of Green Bay increased from 3,317,000...
Status of development of selected ground-water basins in Utah
H. E. Thomas, W.B. Nelson, B. E. Lofgren, R.G. Butler
1952, Technical Publication 7
This technical publication consists essentially of abstracts of more detailed reports which have been published. Reference to existing reports are given in the text and in the bibliography, page 114....
Geology of the Quartz Creek Pegmatite District, Gunnison County Colorado
Mortimer H. Staatz, A.F. Trites
1952, Trace Elements Investigations 138
The Quartz Creek pegmatite district includes an area about 29 square miles in the vicinity of Quartz Creek in Gunnison County,. Colo. This area contains 1,803 pegmatites that are intruded into pre-Cambrian rocks. The rocks exposed in the district range in age from pre-Cambrian to Recent. The oldest pre-Cambrian rocks are...

A.J. Lang Jr., J. A. Redden
1952, Trace Elements Investigations 155
The Fourmile area, Custer County, S. Dak., is in pre-Cambrian metamorphic rocks that surround the granitic core of the Black Hills. The area is on the upright limb of an overturned anticline that plunges about 30° S. 10° E. Three new formations of metamorphic rocks are described that have a total...
