Airborne Radiometric Survey of the East Flank of the Big Horn Mountains, Wyoming and Montana (open access)

Airborne Radiometric Survey of the East Flank of the Big Horn Mountains, Wyoming and Montana

Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

Bentonite Deposits of the Northern Black Hills District Wyoming, Montana, and South Dakota

From abstract: The northern Black Hills bentonite mining district includes parts of Crook County, Wyo., Carter County, Mont., and Butte County, S. Dak. Within this district, many beds of bentonite occur interspersed with sedimentary strata of Cretaceous age that have an average total thickness of about 3,000 feet and consist chiefly of marine shale, marl, and argillaceous sandstone. The bentonite beds occur in formations ranging upward from the Newcastle sandstone to the lower part of the Mitten black shale member of the Pierre shale. Tertiary (?) and Quaternary deposits of gravel, sand, and silt are present on extensive terraces, and deposits of such materials also extend along stream courses in all parts of the district.

Toward Soil Security on the Northern Great Plains

"This bulletin deals with soil and water conservation problems which relate to agriculture of the northern Great Plains [of the United States]." -- p. i. "The major portion of this bulletin, beginning on page 18, is devoted to a discussion of the controls and cures for land misuse. These suggested practices, in the main, represent the methods of control that are now being used in the several demonstration areas of the Soil Conservation Service. The use of these practices in a few specific demonstration areas is included in the section beginning on page 47. The last section (p. 76) points out a democratic procedure whereby landowners and operators may effect a more appropriate use of the land through soil conservation districts." -- p. 2
