Abstract: Avalanches with the 10 smallest a-angles found in a coastal climate near Anchorage, Alaska were compared with the 10 smallest examples found in central Colorado. The Colorado examples had a significantly smaller mean value (16.80 compared with 21.30 in Alaska). The higher mobility of the Colorado avalanches is attributed to (1) easily-dispersed dry soft slab releases, (2) a dry, erodable snowcover found throughout the paths in Colorado, and (3) denser vegetation found in the Alaskan run-out zones.
