The crack is at the saddle above Hollywood Spine and the steep climb to the top of The Beast, at around 5K feet. It is easily avoided by ignoring the Yellow Brick Road boot pack and traveling 10 feet further to the west. This feature had many people poking a foot in and stumbling, and could become even more dangerous with a few inches of fresh snow. Lastly, this cornice will definitely collapse as weather gets warmer.
Observed Avalanche Problem #1:
We encountered a ~40ft deep glide crack / snow crevasse on the main boot pack on the Shuksan Arm where human foot traffic is heaviest. The crack is forming as a very large cornice begins its pulling away / creep from a cliff face towards its imminent collapse. The crack is about 20 feet behind the visible edge of the cornice. Of primary concern is that the boot pack travels directly over the top of the cornice where it overhangs the cliff and slope. It could collapse with many people / parties walking on top of it. Also, falling into the crack could prove a serious situation, as the danger of a long fall to becoming wedged and trapped is a real one, particularly considering that almost no backcountry travelers in this area carry ropes or crevasse rescue gear.
