Academics at Prescott College
Kurt Refsnider, Ph.D.
Kurt is a geologist with expertise in geomorphology (processes that shape the landscape), geochronology, and climate science. Drawn to these fields by a desire to understand the world that surrounds us and how it formed, Kurt is passionate about sharing his curiosity with others, helping students build the skillset necessary to make informed observations and interpretations, and increasing scientific literacy. Kurt is an accomplished field geologist, having conducted research in the Scandinavian and Canadian Arctic, throughout the Rocky Mountains, on glaciers, and in caves. His love of the outdoors and extensive field experience results in his classes spending a substantial portion of their time outside.
He is also the founding executive director of Bikepacking Roots, a 501(c)(3) non-profit organization focused on long-distance mountain bike route development and advocacy for backcountry trail access, public lands, and landscape conservation.
Ph.D. (Geology), University of Colorado, Boulder, 2011
M.S. (Geology), University of Wisconsin, Madison, 2006
B.A. (Geology), University of Minnesota, Morris, 2004
Kurt's research revolves around the themes of landscape evolution, Quaternary climate change (the past ~2.7 million years), and cosmogenic radionuclide applications. Recent projects have ranged from documenting changes in alpine bedrock erosion rates in the Southern Rocky Mountains over the past 4 million years using cave sediments to investigating Laurentide Ice Sheet erosion over the past 2.5 million years in the High Canadian Arctic. Kurt is also interested in understanding spatial patterns in climate during the Last Glacial Maximum (~20,000 years ago) and the influence these patterns had on mountain glaciers in the western United States.
