Abstract

The eastern Klamath Mountains of northern California are cut sharply by an arcuate scarp that forms the west wall of a depression containing Pliocene to Holocene lava rocks. This depression may have formed by collapse along hidden concentric fractures over a batholith and, if so, reflects the shape and areal extent of the body. Large depressions enclosing other volcanic fields are evident on small-scale satellite imagery. If such depressions overlie still hot or even molten batholithic bodies, analysis of satellite imagery might delineate the areal extent of associated geothermal resources.
