Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Gillette quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

From introduction: This study is a comprehensive investigation of altered sandstone associated with uranium deposits near Pumpkin Buttes in the Powder River Basin of Wyoming, and the detection of such alteration using remote sensing technology. The purpose of this study is two-fold: 1) to develop video image processing techniques that will preferentially enhance areas of alteration associated with uranium deposits and enable mapping of these areas, and 2) to investigate the spectral, geochemical, and mineralogical characteristics of altered areas which make them detectable on remote sensor data. Once these video processing techniques have been defined, they may be applied as exploration tools to new areas with similar surface and geological environments. In this way, remote sensing can serve as a valuable tool for uranium exploration.

From abstract: From September 15 to September 28, 1978, geoMetrics, Inc., collected 4320 line miles of high sensitivity airborne radiometric and magnetic data in Wyoming and Nebraska within two 1° x 2° NTMS quadrangles (Torrington and Casper).

This report presents uranium and other elemental data as part of the National Uranium Resource Evaluation which is designed to provide improved estimates of the availability and economics of nuclear fuel resources and to make available to industry information for use in the development and production of uranium resources.

This report presents the findings of the analyses made for a fifty-eight mile stretch along the Yampa River in Colorado. It contains maps, graphs, and tables.

Abstract: The alluvial aquifer along the Greybull River consists principally of the Greybull terrace deposits and the flood-plain alluvium but also includes the Burlington terrace deposits and the flood-plain alluvium but also includes the Burlington terrace deposits east of Burlington, the McKinnie terrace, and the younger, generally undissected alluvial-fan deposits. Well-log data and 18 surface-resistivity measurements at four localities indicate that the thickness of the alluvial aquifer is as much as 60 feet thick only near Burlington and Otto. The most favorable area for development of ground water from the alluvial aquifer is near Burlington and Otto where relatively large amounts of water can be obtained from the Greybull terrace deposits and the flood-plain alluvium. Elsewhere, the deposits of the alluvial aquifer yield only small amounts of water to wells.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Casper quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

The following report is the first in a series of volumes presenting data recorded during the months of August and September, 1978, from a radiometric and magnetic survey taken in four quadrangles between eastern Wyoming, North and South Dakota, and southern Montana (Newcastle, Gillette and Ekalaka).

The following report is the first in a series of volumes presenting data recorded during the months of August and September, 1978, from a radiometric and magnetic survey taken in four quadrangles between Wyoming and southern Montana (Forsyth, Hardin, Sheridan, Arminto, Newcastle and Gillette)

This report contains data from a survey taken between August 11 and August 27, 1978 on the high sensitivity airborne gamma-ray spectrometer and magnetometer over the Ashton quadrangle in Idaho, Montana, and Wyoming.

From introduction: The purpose of this study was to determine the magnitude of some effects of an abandoned surface coal mine on the hydrologic environment. Specific objectives were (1) to define areas of erosion and deposition; (2) to determine if the sediment yield from an undisturbed drainage basin was less than that from a drainage basin partly disturbed by mining activity; and (3) to determine if there were differences in chemical composition of hillslope materials, sediment, and pond water in the two basins.

This report presents the likely and substantial impact that expanded coal production and conversion will have on water in the Yampa River Basin, Colorado and Wyoming. It contains maps and graphs.
