One of the first major projects of the U.S. Continental Scientific Drilling Program (U.S. Geodynamics Committee, 1979) took place in 1986, in the Salton Sea geothermal field (SSGF), in the lower desert of California. A research borehole reached a depth of 3.22 km, and encountered a temperature of 355°C in rocks demonstrating a transition from unconsolidated sediments to hornfelses of lower amphibolite facies. Because drilling for geothermal steam was yielding disappointingly little scientific results, in October 1982 we proposed research drilling in the SSGF to the U.S. Department of Energy (Elders, 1985). Eventually the project cost grew to U.S. $9.3 million, including $2.65 million for scientific studies, funded by the U.S Department of Energy, the U.S Geological Survey, and the National Science Foundation (Aducci, Klick, and Wallace, 1986). In all, some 40 different science and technology development projects were involved (Sass and Elders, 1986).
