This geologic map database for the El Mirage Lake area describes geologic materials for the dry lake, parts of the adjacent Shadow Mountains and Adobe Mountain, and much of the piedmont extending south from the lake upward toward the San Gabriel Mountains

This data set maps the soil-slip susceptibility for several areas in southwestern California. Created using Environmental Systems Research Institute's ARC/INFO software, the data base consists of raster maps containing grid cells coded with soil- slip su

Gravity data were compiled, collected, and edited to produce an isostatic gravity map of the Los Angeles 30 x 60 minute quadrangle, California. This record focuses primarily on the principal facts, that is, gravity observations, and the corrections made

The San Bernardino 30'x60' quadrangle, southern California, is diagonally bisected by the San Andreas Fault Zone, separating the San Gabriel and San Bernardino Mountains, major elements of California's east-oriented Transverse Ranges Province. Included i

The 17 January 1994 Northridge, California, earthquake (M=6.7) triggered more than 11,000 landslides over an area of about 10,000 km². Most of the landslides were concentrated in a 1,000-km² area that includes the Santa Susana Mountains and the mountain

The Santa Ana Quadrangle is in the northern part of the Peninsular Ranges Province as defined by Jahns (1954), except for the northeast corner, which is underlain by basement rocks of the Transverse Ranges Province. A summary of the general geology of th

Dust samples taken annually for five years from 55 sites in southern Nevada and California provide an unparalleled source of information on modern rates of dust deposition, grain size, and mineralogical and chemical composition. The relations of modern d
