The following preliminary report is a computer analysis of HSSR data from the Montrose 1x2 Quadrangle, Colorado.

The following appendix contains petrographic photomicrographs of uranium anomalies in Waterloo Gulch, Colorado.

"The purpose of this project was to evaluate and assess the Miocene Browns Park Formation of a part of the Maybell district in the Sand Wash Basin in Moffat County, Colorado, as an intermediate-grade uranium resource"

Tables providing data related to rock and water samples collected for the study analyzed for uranium favorability, including sample number, quadrangle name, county, coordinates, geologic code, and elemental analyses. During field work, lithologic and structural features were noted, and samples were collected for gamma-ray spectroscopic, geochemical, and petrologic analyses performed at Grand Junction. The gamma-ray spectroscopic and geochemical analytical results are reported in this dataset.

Photomicrographs of core samples submitted for petrographic analysis from Moffat and Routt Counties in northwest Colorado collected for the Sand Wash Basin Drilling Project, which identified areas in the region favorable for uranium occurrences.

Logs describing lithologic characteristics of samples collected from the project area described using a binocular microscope or hand lens and recorded on standard Bendix Field Engineering Corporation (BFEC) logging forms.

The purpose of this report is to summarize the information obtained by the project, to make geologic interpretations of the information, and to transmit the information and interpretations of the information to the U.S. Department of Energy and the Geology Division of Bendix Field Engineering Corporation, Grand Junction Colorado.

"Field and laboratory data are presented for 1,416 water samples from the Limon Quadrangle, Colorado. The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee."

Recorded data taken from field samples of filtered spring, stream, and well water, and acidified stream and lake water from the Limon quadrangle in Colorado.

Recorded laboratory analysis for samples of filtered spring, stream, and well water, and acidified stream and lake water from the Limon quadrangle in Colorado.

A report characterizing known uranium occurrences in the Montrose Quadrangle and to find other areas in the quadrangle with similar characteristics

Color photographs of geologic maps, Landsat imagery, and density slices for the Montrose quadrangle, Colorado. Also included is a color composite for the COCH-1 classification scheme.

"Results of a reconnaissance geochemical survey of the Scottsbluff Quadrangle are reported. Field and laboratory data are presented for 567 groundwater and 402 stream sediment samples. statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and a 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."
