Abstract
During the summer of 1979, the U.S. Geological Survey conducted a geophysical study of the Lassen Known Geothermal Resource Area (KGRA) in northern California. The only data available before this study were a regional geological map and gravity surveys of the Susanville 2° sheet. As part of the USGS work, audio-magnetotelluric (AMT) and magnetotelluric (MT) sounding were made in this area, along with E-field ratio telluric and self potential transverses. Data obtained with the four techniques used correlated quite well and delineated two major areas of low resistivity's within the KGRA.
