Geothermal drilling in the Cascade Range: Preliminary results from a 1387-m core hole, Newberry Volcano, Oregon

Authors


Abstract

The Cascade Mountain Range, which consists of a series of Quaternary and late Tertiary andesitic volcanos that extend from Northern California to Southern British Columbia, is a geologic province with immense potential for the generation of electricity from geothermal energy resources. The geothermal potential for the Cascades Province may well be thousands if not tens of thousands of megawatts [see Bloomquist et al., 1985]. Yet to date there are no geothermal power plants operating in the Cascades Province, and none are planned. Furthermore, except for the obvious heat sources represented by the active volcanos, very little is known about the geothermal resources in the Cascades.
