Purpose: This study was conducted in order to assess the character and extent of Tertiary volcanic rocks and volcanic-derived sedimentary rocks as potential uranium host and (or) source rocks.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Baker National Topographic Map segment (NL 11-11 quadrangle) including a description of the program and results.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Klamath Falls National Topographic Map segment (NK 10-6 quadrangle) including a description of the program and results with the flight line profile data and statistical analysis results.

Results of the Lakeview detailed geochemical survey are reported. Field and laboratory data are reported for 231 groundwater, 881 stream sediment, and 303 stream water samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.
