Map and survey information of the the Aravaipa Valley area in Arizona, including information on well depths, irrigated areas, approximate boundaries, and arbitrary boundaries of ground-water area, as well as general hydrologic data and selected references.

This report includes two maps of the same location, one describing water-level contour, well depth in which depth to water was measured, the other describing well from which water sample was collected and irrigated areas. It includes a letter from the district chief of the United States Department of the Interior to users of the geological survey hydrologic data.

Map of the Okanogan River Valley, Republic-Sanpail River Area and Upper Columbia River Valley with surrounding areas in Washington; stippling marks areas covered by the uranium study in the region. Scale 1:250,000.

Five structure maps showing favorable areas for vein uranium deposits Badger Flats - Elkhorn Thrust project area created for a geologic and geochemical study of the Precambrian igneous and metamorohic rock zones in the project area.

From addendum: Two types of analyses for uranium in the stream-sediment samples are presented. One split of the stream-sediment samples was sent to Resource Associates of Alaska's laboratory, where they were analyzed for U by the fluormetric method after acid extraction. This is the method employed for U by most laboratories. The completeness of uranium extraction unavoidably varies with the particular type of uranium-bearing minerals present and possibly with the amount of iron, manganese, and carbonaceous material present, which can interfere with the extraction. Analyses by the method are shown in the text and appendix columns with the designation "RAA."
