Mineral resource potential map of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas counties, Colorado
Karin E. Budding, Steven E. Kluender
1983, Miscellaneous Field Studies Map 1542-C
A geologic and geochemical investigation and a survey of mines and prospects have been conducted to evaluate the mineral resource potential of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas Counties, in south-central Colorado. The·study area is underlain by sedimentary rocks of Paleozoic to Tertiary age (Johnson, 1969)....
Reconnaissance map showing thickness of volcanic ash deposits in the greater Hilo area, Hawaii
Jane M. Buchanan-Banks
1983, Miscellaneous Field Studies Map 1499
This study was undertaken to determine the thickness and distribution of volcanic ash deposits in the greater Hilo area, Hawaii, as a step toward evaluating their susceptibility to failure during earthquake shaking. On several occasions their instability has resulted in serious damage. For example, the 1868 earthquake (m=7+), following a...
Structure maps and seismic stratigraphy of the Yakataga segment of the continental margin, northern Gulf of Alaska
T.R. Bruns, W. C. Schwab
1983, Miscellaneous Field Studies Map 1424
Multichannel seismic-reflection data show the late Cenozoic structure, seismic stratigraphy, and geologic history of the Yakataga segment of the continental margin, between Icy Bay and Kayak Island, northern Gulf of Alaska. The structure of the Yakataga segment consists of broad folds and associated thrust faults beneath the continental shelf and...

P.O. Abbott, Arthur L. Geldon, Doug Cain, Alan P. Hall, Patrick Edelmann
1983, Water-Resources Investigations Report 83-132
Area 61 is located on the Colorado-New Mexico boundary in Huerfano and Las Animas Counties, Colorado, and Colfax County, New Mexico, and includes the Raton Mesa coal region. The 5 ,900-square-mile area is an asymmetrical structural trough bounded by the Rocky Mountains on the west and the Great Plains on...
Habitat Suitability Index Models: Longnose sucker
Elizabeth A. Edwards
1983, FWS/OBS 82/10.35
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Longnose sucker (Catostomus catostomus), a freshwater fish. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater areas of the continental...
Habitat Suitability Index Models: Fisher
Arthur W. Allen
1983, FWS/OBS 82/10.45
The fisher (Martes pennanti) is the largest member of its genus and is found only i n North America (Powell 1982). Within the contiguous United States, indigenous and reintroduced populations presently inhabit portions of the Appalachian Mountains from New England south to West Virginia in the east; northern Wisconsin, Minnesota,...
