Habitat Suitability Index Models: Eastern meadowlark
Richard L. Schroeder, Patrick J. Sousa
1982, FWS/OBS 82/10.29
Habitat preferences of the eastern meadowlark (Sturnella magna) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. Habitat use information is presented in a synthesis of the literature on the species-habitat requirements of the eastern meadowlark, followed by the development of the...
FLOWCHART; a computer program for plotting flowcharts
Bernice Bender
1982, Open-File Report 82-999
The computer program FLOWCHART can be used to very quickly and easily produce flowcharts of high quality for publication. FLOWCHART centers each element or block of text that it processes on one of a set of (imaginary) vertical lines. It can enclose a text block in a rectangle, circle or...
Maps showing locations and descriptions of radiocarbon-dated samples from central and northern California
Carol A. Price
1982, Miscellaneous Field Studies Map 1321
This compilation includes radiocarbon dates and other pertinent information about samples from northern and central California, principally north of latitude 36°, drawn largely from Radiocarbon, Science, unpublished data of U.S. Geological Survey geologists, and other published and unpublished data brought to the author's attention as of January 1981. It includes...
Mineral resource potential map of the Rock Pile Mountain Wilderness Study area, Madison County, Missouri
Walden P. Pratt, Ralph L. Erickson, Clarence Ellis
1982, Miscellaneous Field Studies Map 1339-B
Although the Rock Pile Mountain Wilderness Study Area is within the general boundary of the Southeast Missouri mining district, it has no record of mineral production and there is no mining or prospecting activity at present. Exploratory drill holes on private land along the west side of the area encountered...
Test well DO-CE 88 at Cambridge, Dorchester County, Maryland
Henry Trapp, L.L. Knobel, Harold Meisler, P.P. Leahy
1982, Open-File Report 82-1015
Test well DO-CE 88 at Cambridge, Maryland, penetrated 3,299 feet of unconsolidated Quaternary, Tertiary and Cretaceous sediments and bottomed in quartz-monzonite gneiss. The well was drilled to provide data for a study of the aquifer system of the northern Atlantic Coastal Plain. Twenty-one core samples were collected. Six sand zones...
Position of the saltwater-freshwater interface in the upper part of the Floridan Aquifer, southwest Florida, 1979
K.W. Causseaux, J. D. Fretwell
1982, Open-File Report 82-90
Ground-water withdrawals in southwest Florida are increasing because of urban growth, industrial expansion and increased agricultural irrigation. As a result, the potentiometric surface of the Floridian aquifer has been lowered in some areas, allowing seawater to encroach into the aquifer and threaten the freshwater resources of the area. Effective management...
Mineral resource potential map of the Bell Mountain Wilderness Study Area, Iron County, Missouri
Walden P. Pratt, Ralph L. Erickson, Clarence E. Ellis
1982, Miscellaneous Field Studies Map 1178-B
Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or...
Multielement chemical and statistical analyses from a uranium hydrogeochemical and stream-sediment survey in and near the Elkhorn Mountains, Jefferson County, Montana. Part I: Surface water
V. J. Suits, K. J. Wenrich
1982, Open-File Report 82-203-A
Fifty-two surface-water samples, collected from an area south of Helena, Jefferson County, were analyzed for 51 chemical species. Of these variables, 35 showed detectable variation over the area, and 29 were utilized in a correlation analysis. Two populations are distinguished in the collected samples and are especially evident in the...
Mineral resource potential map of the Gila-San Francisco Wilderness Study Area, Graham and Greenlee counties, Arizona
Donlad H. Richter, Douglas P. Klein, Viki A. Lawrence, Michael Lane
1982, Miscellaneous Field Studies Map 1315-B
The mineral resource potential of the Gila-San Francisco Wilderness Study Area (AZ-040-022/023/024) is low (fig. 2). Although favorable geologic environments for placer gold deposits and manganese vein deposits are present in the study area, the probability of discovering economically exploitable deposits of these metals is low, and not encouraging. Even...
Mineral resource potential map of the Muddy Mountains Wilderness Study Area, Clark County, Nevada
Robert G. Bohannon, Andrew M. Leszcykowski, Leon E. Esparza, Clayton M. Rumsey
1982, Miscellaneous Field Studies Map 1458-C
The Muddy Mountains Wilderness Study Area (WSA 050-0229), Clark County, Nevada, has a high potential for mineral deposits of calcium borates and lithium. The known and potential mineral deposits are concentrated in the east-central and south-central parts of the study area (see map). Zeolites (in particular clinoptilolite) are present in...
