OSTI ID:5014169
As part of the Washington geothermal exploration program, the Division of Geology and Earth Resources has been involved with studies of the state's major volcanoes and volcanic fields. The first major geothermal project by the Division involved geologic mapping and the drilling of 5 temperature gradient/heat flow holes in the Indian Heaven area in 1975. Funding was provided by the National Science Foundation. From 1980 to 1983, US Department of Energy contracts funded the geochemical analysis of over 100 samples from Indian Heaven and surrounding volcanic fields, and lead to the dating of several of the flows. Uncertainties about the existing age date determinations discouraged attempts to formulate a meaningful time-space-composition-volume model for the southern Cascade Range volcanic fields. With the promise of better age dating techniques and laboratories, the Division set out to improve the understanding of these rocks, with the hope of developing a new, more detailed and accurate model. This project was part of a larger program of temperature gradient and heat flow drilling in the southern Cascades Range. Funding for the age dates was provided through an existing US Department of Energy grant to the University of Arizona.
