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.

The purpose of this investigation was to characterize the population dynamics of the benthos of selected pristine thermal springs.

Pair of brown suede boots. Almost knee-high, the boots are constructed as slip-on rounded-toe shoes or moccasins with added segments on the quarter to create the length of the boots. At the top, the suede of the boots is folded over outwards forming a pocket for a drawstring around top and a band of suede fringe around the outside of the boot. Indistinct trademark/logo stamped on sole. Illegible stamped mark inside boots. Referred to as "Squaw Boots", these were worn by the donor who acquired them in 1968 from the Fishing Bridge Store, in Yellowstone National Park.

A report which includes 200,000 square miles in the southern part of the Williston basin of North Dakota, South Dakota, and Montana. The Devonian rocks consist mostly of marine carbonate, evaporite, and shale beds.

This report studies Devonian rocks in an approximately 200,000-square-mile area between Williston Basin, central Montana, and north-central Wyoming.

A report about two new geologic formations in Wyoming. The Foote Creek Formation consists of beds of fine-grained sandstone with shale, siltstone, and coal beds. The Dutton Creek Formation consists of beds of coarse-grained locally conglomeratic sandstone.

From introduction: Geologic mapping of the Carlile quadrangle, which includes one of several uranium-producing areas in northeastern Wyoming, was undertaken to provide a detailed geologic map that could be used as an aid to further exploration for uranium deposits; to study in detail the known uranium deposits to determine whether or not there are any relations among structure, stratigraphy, lithology, and uranium deposits; and to outline, insofar as possible, areas favorable for more detailed exploration for uranium.

A report about the Powder River Basin in northeastern Wyoming which is a physiographic unit bounded on the west by the Bighorn Mountains. There are sedimentary rocks which range in age from Cambrian to Oligocene.

This report follows the geological field studies of uranium deposits near Pumpkin Buttes in the central part of the Powder River Basin, Wyoming, and eventually moving south of the basin.

A report which presents the geologic results of an exploration program in the Lost Creek area by the U.S. Geological Survey in 1951-52 on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

This report presents the geologic results of an exploration program in the Lost Creek schroeckingerite deposits in northern Sweetwater County, Wyoming.

From introduction: This report on the geology of the Powder River Basin is one of a series of reports by the Geological Survey on sedimentary basins in the United States.

Letter from Reed Larson to Harris Leon Kempner discussing how right to work law has progressed over the past year. And few new non right to work states also initiated this law. He also wrote about how Harris Financial support helped achieve this and hopes that Harris does the same the next following years.
