Letters from concerned citizens to the Defense Base Closure and Realignment Commission (BRAC)in response to the recommendation regarding Ellsworth Air Force Base.

Report issued by the U.S. Bureau of Mines on the pegmatite deposits found near Tinton, South Dakota. The properties, and geology of the deposits are presented. This report includes tables, and maps.

From introduction: This report evaluates four possible types of subsurface reservoirs for radioactive wastes in the Williston basin.

The following report provides results from a geochemical survey for Rapid City, South Dakota. Field and laboratory data are presented for 417 groundwater and 447 stream sediment samples.

Report discussing the results of core drilling in the Mendenhall Area of Harding County, South Dakota. This drilling was aimed at collecting data regarding uranium-bearing lignite. The report provides information regarding drilling operations, stratigraphy of the area, structure, and lignite deposits.

Appendices containing data on uranium availability in the Lemmon Quadrangle to accompany a report on U.S. uranium resources in South and North Dakota.

From abstract: This report is intended to supplement the brief interpretation of geochemical data presented in the "Hydrogeochemical and Stream Sediment Detailed Geochemical Survey for the Edgemont South Dakota; Wyoming" report (Butz, et al, 1980).

From Introduction: "The Lemmon Quadrangle, South Dakota and North Dakota, was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

A report regarding the results of core drilling for uranium-bearing lignites in the Bar H Area, Slim Buttes, Harding County, South Dakota. This report is done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission

A report regarding the results of core drilling for uranium-bearing lignite, Mendenhall area, Harding County, South Dakota. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Documentation outlining characteristics of field data samples taken in the Rapid City quadrangle.

"Results of a reconnaissance geochemical survey of the O'neill Quadrangle are reported. Field and laboratory data are presented for 23 groundwater and 292 stream sediment samples. Statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and producing horizon map for the survey area are provided. Pertinent geologic factors that may be of significance in evaluating the potential for uranium mineralization are briefly discussed." (from Abstract)
