Holocene And Modern Geomorphic Response To Forest Fires And Climate Change In Yellowstone National Park, Grant A. Meyer

Earth and Planetary Sciences ETDs

The Yellowstone fires of 1988 provided an opportunity to observe the geomorphic impact of widespread, intense forest fires on a mountain environment. Post-1988 fire-related sedimentation events also served as geomorphological and sedimentological analogs which were used to interpret a Holocene stratigraphic record of fire-related alluvial activity. Research focussed primarily on the steep-walled glacial trough valley of Soda Butte Creek, and parts of the Slough Creek and Lamar River drainages in northeastern Yellowstone.

All of the examined major post-1988 fire-related sedimentation events involved the generation of widespread surface runoff from brief, intense summer convective-storm precipitation on steep slopes in intensely burned …
