Gold in the United States, exclusive of Alaska and Hawaii
Albert Herbert Koschmann, M.H. Bergendahl
1962, Mineral Investigations Resource Map 24
The accompanying map shows the distribution of the principal gold mining districts in the United States (excluding Alaska and Hawaii). Only those districts that have produced 10,000 ounces of gold or more are shown. Gold ore reserves were not considered, and the types of deposits are not shown. Based on...
Asbestos in the United States, exclusive of Alaska and Hawaii
A.H. Chidester, A. F. Shride
1962, Mineral Investigations Resource Map 17
The asbestos deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. The principal mineralogic types of asbestos (chrysotile and amphibole) are indicated by the shape of symbols, and the relative importance of the deposit is indicated by the size of symbols. The text...
Silver in the United States, exclusive of Alaska and Hawaii
Edwin Thor McKnight, W.L. Newman, Harry Klemic, A. V. Heyl
1962, Mineral Investigations Resource Map 34
The productive silver districts in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. Only those districts known or believed to have contained 100,000 troy ounces or more silver are shown. Three size categories, based on production and estimated reserves, are distinguished and indicated by...
Explorations for water supplies on the public domain, 1960
William Stewart Eisenlohr
1962, Circular 461
In making reconnaissances for water supplies on the public domain as part of the Soil and Moisture Conservation Program of the Department of the Interior, the Geological Survey obtains information on the availability of water that is useful for other purposes or in other areas. This report contains the information...
Current studies of the hydrology of prairie potholes
Jelmer B. Shjeflo
1962, Circular 472
The prairie potholes in the North-Central States and in Canada are of glacial origin. Because many of them contain ponds or marshes, they are important in the production of livestock and waterfowl. The objective of the present investigation is to determine the amount of water that accumulates in and is...
Floods of December 1961 in Mississippi and adjoining states
James D. Shell
1962, Circular 465
Widespread floods occurred over parts of Mississippi, Louisiana, and Alabama after heavy rains during December 18, 1961. A series of low-pressure systems produced as much as 19 inches of rainfall in some areas. Heavy rainfall, 7 to 11 inches, on December 10 resulted in outstanding floods on small streams in...
Notes on earth fissures in southern Arizona
G.M. Robinson, D.E. Peterson
1962, Circular 466
This report describes earth fissures at six sites in southern Arizona. These notes are preliminary to a more extensive study and detailed analysis being prepared by hydrologists in the Water Resources Division. Earth fissures were first recorded in Arizona in 1927, and have been noticed with increasing frequency since 1949....
Ground-water studies and analog models
Charles Joseph Robinove
1962, Circular 468
Hydrologists make ground-water studies to aid managers and users of water resources in solving their problems in the development and management of ground water. Geologic and hydrologic information provides the basic knowledge for construction of electric analog models that portray the ground-water system in miniature. Analog models can be analyzed...
A national network of hydrological benchmarks
Luna Bergere Leopold
1962, Circular 460-B
We are engaged in great national programs of water control and development. An expanding population demands ever-increasing supplies of the natural resources which are to be found in or upon the landscape soil, water, minerals, food, timber, and fiber. By his works, by his extractions, man's mark upon his environment...
The man and the hill

1962, Circular 460-A
He was sitting on a large slab of rock. As he looked at the cloud of dust hanging hazily on the horizon, the piece of antler and the block of flint he held in his hand hung as if they were suspended from their previous rapid motion. The man gazed...
Floods in New Mexico, magnitude and frequency
Leon A. Wiard
1962, Circular 464
This report presents a method of determining the magnitude and frequency of floods that can be expected in New Mexico The discharge of the mean annual flood for various regions in the State is defined. Curves relate mean annual flood and drainage area. Drainage area was the only basin characteristic...
