Comments
[Forecaster comment:] Dimensions are estimates. We also received the following information from the party involved:
Ski cut the NNW starting zone on Sunset Peak. Cracked behind me and propagated down the ridge. Ran to the ground. Exited the chute w some speed and triggered another slab skiers right. This too went to the ground. Prolly 3’ crown here. Finished on boilerplate ice and was moving very fast.
