Erich Peitzsch, Ph.D
My main interests lie in the realm of snow and ice.
Research Interests
Previous projects include investigating wet snow avalanche processes, such as water movement in the snowpack and its implications for wet slab avalanches. Working as an avalanche forecaster for the spring opening of the Going-to-the-Sun Road in Glacier National Park allows me to continue work on wet snow avalanche projects such as glide slab avalanches. I am also interested in investigating ecological change associated with avalanches, avalanche runout probability, and the relationship between climate and avalanches. Other research interests include monitoring mass balance of small mountain catchment glaciers.
