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...
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...
The use of soils and paleosols for interpreting geomorphic and climatic history of arid regions
John Miller, Luna Bergere Leopold
1953, Research Council of Israel Special Publication 2
The study of modern surface soils, and ancient weathering zones, which occur either buried or as surface relicts, has contributed materially to understanding the complex events of the glacial and post-glacial period both in glaciated areas and in regions not influenced by glaciation. Most work of this kind in the...
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...
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...
Geology and pegmatites of part of the Fourmile area, Custer County, South Dakota
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...

Leonard Cameron Halpenny
1952, Open-File Report 172
This report is a resume' of the principal facts collected by the Geological Survey in the period 1890-1952 about the ground-water resources of the Gila River basin and certain other areas in Arizona. Since 1939 the Geological Survey has been making ground-water investigations on a continuing basis in cooperation with...
