Group: Summary
  The purpose of the survey was to locate more precisely and
  characterize the Rialto-Colton fault, a strand in the San Jacinto
  fault zone. The information developed during this study will be used
  in ground-water models by the USGS Water Resources Division and for
  the purposes of deciphering the complex basin geometry and tectonic
  history in this area to help understand the development of similar
  strike-slip basins.
  
  New gravity measurements in the vicinity of San Bernardino, California
  were collected to help define the characteristics of the Rialto-Colton
  fault.  The data were processed using standard reduction formulas and
  parameters.  Rock properties such as lithology, magnetic susceptibility
  and density also were measured at several locations.
