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...
Lead in the United States, exclusive of Alaska and Hawaii
Edwin Thor McKnight, Allen Van Heyl, William Louis Newman
1962, Mineral Investigations Resource Map 15
The productive lead districts in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. The map is at a scale of 1: 3,168,000, (50 miles to the inch). Only those districts known or believed to contain 1,000 short tons or more of lead are shown;...

Arthur R. Kinkel Jr., N. P. Peterson
1962, Mineral Investigations Resource Map 13
The copper districts in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. In compiling the map, the estimated total quantity of copper present before mining was used to assign districts to size categories, and both production and reserves are included without distinction as to...
Vanadium in the United States, exclusive of Alaska and Hawaii
Richard Philip Fischer
1962, Mineral Investigations Resource Map 16
The productive and potential raw material sources of vanadium in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. This map is at the scale of 50 miles to the inch. The text accompanying the map briefly describes the major geologic types of deposits of...
Epigenetic uranium deposits in the United States, exclusive of Alaska and Hawaii
Arthur Pierce Butler, Warren Irvin Finch, William Stephens Twenhofel
1962, Mineral Investigations Resource Map 21
Productive and unproductive deposits of uranium in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. These deposits constitute the actual and some of the potential domestic raw-material sources of uranium. Other potential sources of uranium similar to these known deposits remain to be discovered...
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...
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...
Tungsten in the United States, exclusive of Alaska and Hawaii
D.M. Lemmon, Ogden L. Tweto
1962, Mineral Investigations Resource Map 25
The accompanying map shows the tungsten deposits of the United States (exclusive of Alaska and Hawaii). The relative importance of the deposits, groups, or districts is shown by four symbols, indicating tungsten contents of: (1) greater than 10,000 short tons of tungsten metal, (2) 10,000 to 500 tons, (3) 500...
The meteorologic phenomenon of drought in the Southwest
H. E. Thomas
1962, Professional Paper 372-A
The recent drought is one of several which have been recorded in the arid Southwest in the past century. In regions where precipitation comes chiefly from a single source, as in California and the Great Plains, prevailingly dry periods have alternated with wetter periods, each lasting 10 to 15 years....
Salinity of the Delaware Estuary
Bernard Cohen, Leo T. McCarthy Jr.
1962, Water Supply Paper 1586-B
The purpose of this investigation was to obtain data on and study the factors affecting the salinity of the Delaware River from Philadelphia, Pa., to the Appoquinimink River, Del. The general chemical quality of water in the estuary is described, including changes in salinity in the river cross section and...
Ground-Water Reconnaissance at Pinnacles National Monument, California
R. E. Evenson
1962, Water Supply Paper 1475-K
Ground-water supplies at Pinnacles National Monument have been obtained from springs that occur in fractures and along bedding planes of volcanic flows and deposits, and from springs discharged from perched water in a sedimentary fanglomerate formation. The spring-water yield is barely adequate to supply existing camp facilities, and therefore a...
