Fraser Goff received a B.S. in chemistry from San Jose State University (1971) and his Ph.D. in Earth Science from University of California Santa Cruz (1977), where his thesis dealt with igneous petrology and geochemistry of basalt. During this period he worked at the US Geological Survey in Menlo Park, California (1969-1977) on geothermal and volcano projects. From 1978-2004 Fraser was employed by Los Alamos National Laboratory, New Mexico working on a series of geothermal, volcano, and environmental projects. He was Chief Scientist and Principal Investigator on three high-temperature scientific wells in the Valles Caldera (1983-1991). He was head geochemist during drilling of four exploration wells in Central America for US AID (1985-1992). Since 2004 Fraser has been adjunct professor at University of New Mexico and New Mexico Institute of Technology, a member of the StateMap Program (NMBG&MR), and a private consultant. Fraser led or co-led long-term projects to investigate the chemical and isotopic composition of magmatic and geothermal fluids, and to develop remote sensing techniques to analyze gas compositions from active volcano plumes. He has worked on about 40 geothermal systems and 15 active volcanoes worldwide during his career and has been author or co-author on more than 100 referred journal publications. Since 2004 Fraser has been author or co-author on 15 geologic maps. In 2009 he published Valles Caldera – A Geologic History (114 p., University of New Mexico Press). Fraser is now completing a geologic map and report on Mount Taylor, New Mexico’s “other” famous volcano.
