USGS Open-File Report 02-353: Gravity map and data of the eastern half of the Big Bear Lake, 100,000 scale quadrangle, California and analysis of the depths of several basins

Gravity map and data of the eastern half of the Big Bear Lake, 100,000 scale quadrangle, California and analysis of the depths of several basins

By Carter Roberts, Robert Jachens, Allan Katzenstein, Gregory Smith and Russell Johnson

Summary

Gravity surveys are useful tools for helping to understand the 3-dimensional geology of an area. Many gravity measurements were made in the 1960s and 1970s by various groups in order to produce gravity maps covering California at a scale of 1:250,000 for the California Division of Mines and Geology. (For this area see Biehler et. al. 1988.) More recent surveys have focused on specific areas and problems. This report includes new data on the southern portion of the Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms and the Yucca Valley-Joshua Tree-Twentynine Palms area and presents the map and basin analyses that were prepared with these data.
