Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Rapid City quadrangle including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Rapid City quadrangle including a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation maps, flight line and geologic base map, and individual corrected profiles.

From introduction: This volume contains information and survey results pertaining specifically to the Hot Springs NTMS 1:250,000 scale Quadrangle, South Dakota, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

Foreword: This is the eighth of a series of reports covering technical progress on the research and development program being performed in connection with the design of the Pathfinder Atomic Power Plant.

Introduction: This is the fifth of a series of reports covering technical progress on the research and development program being performed in connection with the design of the Pathfinder Atomic Power Plant.

From introduction: This is one of a series of three reports on airborne radioactivity surveys in the United States. The reports contain the 185 airborne anomaly maps issued by the U. S. Atomic Energy Commission as a result of the AEC's aerial surveying program conducted from March 1952 to June 1956; two ground reconnaissance maps of Utah also are included. Most of the reconnaissance was done in the western United States.

From introduction: This report describes briefly the deposits of uranium ore discovered in June 1951 near Edgemont, Fall River County, South Dakota. It is a preliminary report, based upon rapid reconnaissance of a small area around the original discovery. It is intended for those who may be interested in further prospecting a large potential area and in developing and mining the deposits.

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 abstract: Results of a reconnaissance geochemical survey of the Alliance Quadrangle are reported. Field and laboratory data are presented for 543 groundwater and 523 stream sediment samples.

This report presents the results of an airborne radiometric survey that was made of the Inyan Kara group in the Black Hills of South Dakota and Wyoming between March 5 to December 5, 1952.
