About Speakers:

Susan M. Karl
U.S. Geological Survey

Sue earned a BA degree from Middlebury College in 1973, and first came to Alaska in 1973 as a
teacher in the VISTA (Volunteers in Service to America) program. Following that year, she stayed
in Alaska and worked in mineral exploration for RioTinto, WGM, and Urangeschellschaft in 1974-
1976 while taking classes at UAF. In 1977 she transferred to Stanford University and completed a
PhD at Stanford in 1983. She has worked in the Alaskan Geology Section of the USGS Minerals
Program since 1977. Sue has worked all over the state as a mapper and stratigrapher, with
emphasis on sedimentary petrology, igneous geochemistry, and the tectonic setting of mineral
deposits. She is currently working on sedimentary petrology and stratigraphy for the Western
Alaska Range project, the tectonic setting and distribution of Quaternary volcanoes and related
thermal springs in southeast Alaska, PGE sources and the tectonic setting of ultramafic rocks in
southeast Alaska, and REE sources and the tectonic setting of peralkaline granite at Bokan
Mountain in southeast Alaska. Sue is a career member and fellow of numerous professional
organizations, and has been an executive, board member, and/or committee chair in the Alaska
Geological Society since 1990. She especially likes participating on the scholarship committee
and giving a boost to young geologists. Sue's family includes 2 kids in college, 25 dogs, and a cat:
she enjoys hiking, camping, sea-kayaking, river rafting, skiing, dogsledding, and life in Alaska.
