Manganese in the United States, exclusive of Alaska and Hawaii
Max D. Crittenden, Louis Pavlides
1962, Mineral Investigations Resource Map 23
The manganese deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. The deposits have been divided into several genetic types distinguished on the map by symbols. The principal distinction is between syngenetic deposits, in which the manganese was deposited contemporaneously with the enclosing...
Bismuth in the United States, exclusive of Alaska and Hawaii
John Roberts Cooper
1962, Mineral Investigations Resource Map 22
The bismuth-bearing deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. In compiling the map the deposits were classified into two categories: 1) those that have produced bismuth or are regarded as potential sources based on available information (in general, this category includes...
The distribution of tritium fallout in precipitation over North America
L. L. Thatcher
1962, International Association of Scientific Hydrology - Bulletin (7) 48-58
In 1958 the U.S. Geological Survey and the U.S. Weather Bureau jointly conducted a study of tritium fallout distribution over the continental United States, Alaska, and Puerto Rico. The observation period extended from early April to late July in most areas. While this was insufficient to cover the decay side of the...

Benjamin Gildersleeve
1962, Mineral Investigations Resource Map 27
The important deposits of magnesite (MgCO3) and brucite (MgO.H2O) in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. Single deposits and groups of deposits are shown by geometric symbols according to four size categories based on estimated production plus reserves. These categories are: less...
Thorium and rare earths in the United States, exclusive of Alaska and Hawaii
J. C. Olson, J. W. Adams
1962, Mineral Investigations Resource Map 28
The accompanying map shows the location of the principal deposits of thorium and rare-earth minerals in the United States (excluding Alaska and Hawaii). Symbols of different shapes are used to depict deposits of different geologic types, and sizes of symbols denote the relative importance of the deposits. Because of scale...
Structure and stratigraphy of the Pybus-Gambier area, Alaska
Robert Ahlberg Loney
1961, Open-File Report 61-89
The Pybus-Gambier area comprises about 215 square miles of uninhabited land on the southeastern coast of Admiralty Island, southeastern Alaska. The section consists of more than 20,000 feet of intensely folded sedimentary, volcanic, and metamorphic rocks, all probably of marine origin, ranging in age from Silurian(?) to Early Cretaceous, unconformably...
Potential water power of Lake Chakachamna, Alaska
Bruce Lawellin Jackson
1961, Open-File Report 61-74
Lake Chakachamna, in view of its area, altitude, and location on a region of high precipitation and runoff, has a large potential power value. The outflow from the lake, based on limited streamflow records varies from less than 60 cfs to well over 15,000 cfs, with an annual flow in...
