Climbers on the big sleep on Saturday reported strong wind and blowing snow. They witnessed a wind slab that broke above the climb, and estimated that it was large enough to bury, injure, or kill a person.
From obs 2/5/22: "We hiked into Flanders to check out the Big Sleep ice climb. It was super windy with lots of blowing snow and the ice was thin so we decided not to climb it.
We witnessed a sizeable wind slab or sluff pour over the big sleep. It covered the whole climb for a second and probably would've slammed a climber off the route. Maybe 20 x 20 x 6 in slab but thats loose estimate."
