  Description:
    Abstract: Principal facts (gravity observations) for 185 new stations
    Purpose:
      Cenozoic basins in eastern Nevada and western Utah constitute major
      ground-water recharge areas in the eastern part of the Great Basin,
      and our continuing studies are intended to characterize the geologic
      framework of the region. Prior to these investigations, regional
      gravity coverage was variable over the region, adequate in some
      areas and very sparse in others. The current study in Nevada
      provides additional high-resolution gravity along transects in Dry
      Lake and Delamar Valleys to supplement data we established
      previously in Cave and Muleshoe Valleys.
