Preliminary interpretation of a seismic-refraction profile across the Large Aperture Seismic Array, Montana
C.A. Borcherdt, John C. Roller
1968, Open-File Report 68-15
A reversed seismic-refraction profile extending northeastward from Greycliff, Montana, across the Large Aperture Seismic Array (LASA) to Charleson, North Dakota, indicates that the crust of the earth consists of two layers with P-wave velocities of 6.1 km/sec and 6.7 km/sec, and that the upper-mantle velocity is 8.3 km/sec. The Mohorovicic...
Land evaluation studies with remote sensors in the infrared and radar regions
David S. Simonett
1968, Open-File Report 68-250
This paper reviews the literature, especially of the last two years, dealing with remote sensor evaluation of surface and shallow sub-surface characteristics, employing remote sensors in the infrared (1.5p. - 14p.) and radar (0.5 cm - 100 cm) regions. Imaging and non-imaging sensors are examined to assess their current status...
The Mt. Montro kyanite deposit, Grand Bassa County, Liberia
S. Anthony Stanin, Bismark R. Cooper
1968, Open-File Report 68-258
The Mt. Montro kyanite deposit, 14 miles north of Buchanan, Grand Bassa County, Liberia, is near the middle of a belt of kyanite-bearing gneisses and schists that is 9 miles long and 1 mile wide. The deposit, which seems to be the most persistent and the largest single body of...
Hydrology of Crater, East and Davis Lakes, Oregon; with section on Chemistry of the Lakes
Kenneth N. Phillips, A. S. Van Denburgh
1968, Water Supply Paper 1859-E
Crater, East, and Davis Lakes are small bodies of fresh water that occupy topographically closed basins in Holocene volcanic terrane. Because the annual water supply exceeds annual evaporation, water must be lost by seepage from each lake. The seepage rates vary widely both in volume and in percentage of the...
