1981, Open-File Report 81-134
A geologic reconnaissance of the Hot Springs Mountains and adjacent areas, which include parts of the Brady-Hazen and the Stillwater-Soda Lake Known Geothermal Resource Areas, during June-December 1975, resulted in a reinterpretation of the nature and location of some Basin and Range faults. In addition, the late Cenozoic stratigraphy has...

Potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 1981
George R. Schiner, E. C. Hayes
1981, Open-File Report 82-118
This map presents the potentiometric surface of the Floridan acquifer in the St. Johns River Water Management District and vicinity for September 1981. The Floridan acquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs. The potentiometric...

1981, Open-File Report 81-1006
A May 1981 potentiometric-surface map of the Southwest Florida Water Management District depicts the annual low water-level period. Potentiometric levels decreased 10 to 45 feet between September 1980 and May 1981 in the citrus and farming sections of southern Hillsborough, northern Hardee, southwestern Polk, northwestern DeSoto, and Manatee Counties. Water...

Bed form distribution and inferred sand transport on Georges Bank
David C. Twichell
1981, Open-File Report 81-764
Four bed-form provinces have been identified on Georges Bank using sidescan sonar and echo-sounding techniques: large sand waves, small sand waves, megaripples, and featureless sea floor. The large sand waves are found on the bank crest where the surface tidal currents are strongest, and are bordered, north and south, by...

The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. Results must be made available to the public and be submitted to the President...

Behrendt and others (1968) pointed out the close correlation between a belt of extreme gravity lows (Behrendt and Bajwa, 1974) and a zone of precious and base mineral deposits (Tweto and Simms, 1963, fig. 1). Tweto and Case (1972) showed that this belt of gravity lows probably reflects a series...

1981, Open-File Report 81-211
A May 1980 potentiometric surface map of the Suwannee River Water Management District area, Florida, depicts water levels in wells tapping the Floridan aquifer. Compared to the May 1976 potentiometric map of the area, there are no significant differences in the general appearance of the contours. Water levels, however, are...

The Centennial Mountains include parts of Beaverhead County, Montana, and Clark and Fremont Counties, Idaho; the mountains trend east, and the Continental Divide follows their crest (fig. 1). They form a massive, almost impassable barrier between Centennial Valley on the north and the broad expanse of the Snake River Plain...
