Notes
In First Yellowmule, Dave was crossing a low-angle slope and remotely triggered an avalanche in steep terrain from 750' away. This avalanche was 1-2' deep, 250' wide, and ran 200' to the meadow below. The avalanche failed on a layer of buried surface hoar. At the crown, we dug a snowpit and had ECTP10 results on this layer.
Some avalanches we saw/ triggered were on wind-loaded slopes, and others were not. All steep slopes are suspect.
