Aeromagnetic maps of the Latir Peak and Wheeler Peak Wildernesses and the Columbine-Hondo Wilderness Study Area, Taos County, New Mexico
C. K. Moss, G. A. Abrams
1985, Miscellaneous Field Studies Map 1570-C
This report interprets data from a helicopter-borne magnetic survey to help delineate subsurface geology. Such data, acquired near the ground, reflect greater magnetic detail than do data acquired at higher altitude. Data from a high-altitude reconnaissance aeromagnetic survey (U.S. Geological Survey, 1976) are used selectively to assist in the interpretation...
Aeromagnetic maps of the Mazatzal Wilderness and contiguous roadless areas, Gila, Maricopa, and Yavapai counties, Arizona
C. K. Moss, G. A. Abrams
1985, Miscellaneous Field Studies Map 1573-B
The Mazatzal Wilderness and contiguous roadless areas are located in Tonto and Coconino National Forests, west and southwest of Payson, and are almost exactly in the geographic center of Arizona. This is a region of relatively small mining districts and few mines, but occurrences of many different metals are widespread. The...
Reference section for the Minturn Formation (Middle Pennsylvanian), northern Sangre de Cristo Range, Custer County, Colorado
D. A. Lindsey, R. F. Clark, S. J. Soulliere
1985, Miscellaneous Field Studies Map 1622-C
This reference section of the Middle Pennsylvanian Minturn Formation was measured in the northern Sangre de Cristo Range; the section provides a basis for comparison with the type Minturn and with possibly equivalent strata elsewhere in southern Colorado. The name "Minturn" was first applied to strata of Middle Pennsylvanian age...
Evaluation of the ground-water resources of the lower Susquehanna River basin, Pennsylvania and Maryland
James M. Gerhart, George J. Lazorchick
1985, Open-File Report 84-748
Ground water in the 3,458-square-mile lower Susquehanna River basin occupies secondary openings in bedrock. The distribution of openings is a function of lithology, depth, and topography. Local flow systems account for most of the total ground-water flow. Average annual recharge for the lower basin is 1,857 million gallons per day,...
Ground-water levels in Arkansas, spring 1985
Joe Edds, J.L. Spencer
1985, Open-File Report 85-478
The report contains 622 ground-water level measurements made in observation wells in Arkansas in the spring of 1985. In addition , the report contains well hydrographs relating to the Quaternary aquifer and the Sparta Sand aquifers, the most important aquifers with respect to ground-water availability and use in Arkansas. (USGS)...
The Georgia Water-Use Program
Julia L. Fanning
1985, Open-File Report 85-481
WHY COLLECT WATER-USE INFORMATION? Water used in Georgia increased from 5,560 to 6,765 million gallons per day (22 percent) between 1970 and 1980. In 1970 the population of Georgia was about 4,600,000. By 1980 it had rcached an estimated 5,500,000, a 20-percent increase. The amount of irrigated land in the State...
