Map showing evidence for recent fault activity in the vicinity of Antioch, Contra Costa County, California

The U.S. Geological Survey, in cooperation with other federal, state, and local agencies, is studying active and potentially active faults in the counties surrounding San Francisco Bay as past of a program to define and clarify geologic hazards in the region.  Much more detailed information about known faults has been collected; in addition, poorly known or previously unknown zones of demonstrable

Map showing mined areas of the Boulder-Weld coal field, Colorado

Compiled by Raymond E. Lowrie, U.S. Bureau of Mines (1966), and revised by Roger B. Colton, U.S. Geological Survey, assisted by Harold R. Fitch, 1972.In the revision of this map, many mine maps and two unpublished general small-scale maps of the area by F. H. Canis (deceased) and Samuel Tescher (deceased) were used.  Much information was obtained orally from Louis A. Gaz, Consulting Engineer, Lafa

Map showing minimum depth to water in shallow aquifers (1963-72) in the Sugar House quadrangle, Salt Lake County, Utah

The depth to ground water in shallow aquifers in the Sugar Horse quadrangle ranges from zero in areas of springs and seeps to more than 10 feet beneath most of the area shown on the map. The depth to water differs from place to place because of irregular topography, and the varying capability of different rock materials to transmit water. Ground water also occurs under unconfined and confined cond
