Surface-water resources in the Tooele 2° quadrangle, Utah Surface-water resources in the Tooele 2° quadrangle, Utah

This is one of a series of maps that describe the geology and related natural resources of the Tooele 2° quadrangle. The purpose of this map is to describe on a regional scale the availability and chemical quality of surface water and to guide readers to more detailed site-specific information about the resource in this generally semiarid region. Most of the data used to compile this map...

A climatic appraisal of the rehabilitation potential of strippable coal lands in the Green, Yampa, and White River drainage basins, Colorado, Utah, and Wyoming A climatic appraisal of the rehabilitation potential of strippable coal lands in the Green, Yampa, and White River drainage basins, Colorado, Utah, and Wyoming

The study area of this report is defined as the drainage basins of the Green, Yampa, and White Rivers. The Uinta Mountains of northeastern Utah are excluded because of the lack of sufficient reliable and representative climatological records and because of the unlikelihood of surface-mining within these mountains.

Aeromagnetic and interpretation map of the King Range and Chemise Mountain Instant Study Areas, Northern California Aeromagnetic and interpretation map of the King Range and Chemise Mountain Instant Study Areas, Northern California

The data for the aeromagnetic map (sheet 1) of the King Range and Chemise Mountain areas wre collected in 1978 and compiled at a scale of 1:62,500. Northeast-southwest traverses were spaced at 0.8-km intervals at an altitude for 300 m above the ground surface and 600 m above the ocean because of cliffs along the shore. The contour interval is 10 of or 50γ, depending on the steepness of...
