J. M. Norris, W.S. Maura
1985, Open-File Report 85-190
The upper reaches of the North Fork of the Gunnison River have been an area of active coal mining for many years. Recently, concerns about impacts of coal mining on surface-water quality have been raised. To answer these concerns, information on existing, or background, water quality must be known. To...
Sedimentation and water quality in the West Branch Shade River basin, Ohio, 1984 water year
C.J. Childress, R.L. Jones
1985, Open-File Report 85-552
Sedimentation in, and flooding of, the West Branch Shade River and its tributaries have been major concerns of residents and State and local officials. The area was extensively surface mined for coal between the mid-1940 's and the early 1960's. Reclamation efforts immediately after mining were unsuccessful. The results have...
Review of the use of magnetic concentrates in geochemical exploration
W.C. Overstreet, G.W. Day
1985, Open-File Report 85-541
Magnetic concentrates recovered readily by hand magnet from alluvial sediments or panned concentrates have been used successfully in exploration as a geochemical sample medium for Cu, Zn, Co, Cr, Mo, Ni, V, Sn, and Be, particularly in arid environments where alluvial sediments may be contaminated by aeolian debris.

Magnitude and frequency of debris flows, and areas of hazard on Mount Shasta, northern California
W. R. Osterkamp, C.R. Hupp, J. C. Blodgett
1985, Open-File Report 85-425
Debris flows on Mount Shasta, northern California, have occurred frequently during the late Holocene in response to rapid runoff from melting snow and ice. Glacial-meltwater streams that deeply incise unstable pyroclastic and related flow deposits typically from debris flows when high discharge rates cause slope failures within steep-walled gorges. The...
