A preliminary investigation of possible sources of cement rock in the Taft area was made during the latter part of August 1968. Adequate deposits of limestone, clay, quartz conglomerate and sandstone, and pisolitic iron ore, yet no gypsum, were located to support a Cement plant should it prove feasible to...

Geologic setting of Merrill Lake and evaluation of volcanic hazards in the Kalama River valley near Mount St. Helens, Washington
Jack H. Hyde
1970, Open-File Report 70-169
Volcanic rocks and unconsolidated geologic deposits in the upper Kalama River valley were studied in order to determine the kind of catastrophic geologic events that might accompany a future eruption of Mount St. Helens. The chief purpose of the study was to appraise the potential geologic hazards at the site...
LASA anomalies and their relations to crust and upper-mantle structure

1970, Open-File Report 70-170
Body-wave data from nine teleseisms recorded at the Large Aperture Seismic Array (LASA), Montana, have been analyzed. The events were at different azimuths and distances from LASA. Apparent-velocity measurements using arrival-time data at the subarrays differed by about 30 percent for events in the northwest and southeast directions.Apparent velocities were...
Geologic, geochemical, and geophysical investigations in the northern part of the Gilmore mining district, Lemhi County, Idaho

1970, Open-File Report 70-282
Geologic, geochemical, and geophysical investigations in the northern part of the Gilmore (Texas) mining district, Lemhi County, Idaho, indicate an area of anomalous concentrations of lead and silver in glacial deposits. These deposits overlie the probable extensions of the main veins as them are projected northward from the central part...
A proposed streamflow-data program for Utah
G.L. Whitaker
1970, Open-File Report 71-322
An evaluation of the streamflow data available in Utah was made to provide guidelines for planning future programs. The basic steps in the evaluation procedure were (1) definition of the long- term goals of the streamflow-data program in quantitative form, (2) examination and analysis of all available data to determine...
