Quick report
While booting the Sliver and getting through the top of E Hourglass, we had very few signs of instability. The only notable events being one or two very light spindrift events in the couloir. The winds actually felt minimal from the line, but that may have not been the case in surrounding terrain above us. The weather socked in around 11, and started snowing hard. After checking the surprise weather data, it appears to have accumulated 2” over the course of 90 mins prior to the slide. After rappelling into E Hourglass, our party transitioned into ski mode preparing to drop. Right after the first in our group dropped, a slide fed into the couloir from overhead.

Right after the first in our party dropped, we heard a loud roar of moving snow from overhead on Spooky Face. A large mass of snow fed over the skiers left wall and “waterfalled” into the couloir just above the skier. The mass of snow exploded up the opposing face and up the couloir. The skier was caught and carried briefly before being able to escape the slide path. The slide continued well through E Hourglass and into the apron below.
