This report provides results on the geological studies of uranium deposits discovered in the southeastern part of Montana.

This report provides the results to an airborne radiometric reconnaissance made in central Montana, the Sweetgrass Hills and Arch area, and Clancy area of the Boulder batholith that was completed in October 1953. This report is divided into three parts, each area is discussed separately according to its geology, the airborne procedures employed, and the conclusions reached.
