Red Flags Comments
Observed two avalanches that have not been previously reported. The Huge Chute in the Wolverine Cirque appeared to be at least 250 feet wide and up to at least 5 feet deep. The other was Martha's Bowl. This one had been filled in pretty well from past winds. Of note it was connected to the small bowl further to the WSW. Also of note, the lower cliffs in the Marthas Bowl picture indicate that it slide there as well (and this is very unusual). See pictures.
