We had an awesome tour out Owl Creek! While we were gaining an E/NE facing ridge we experienced collapses a number of times as we would travel towards the wind loaded side of the ridge. We also experienced this on a NW slope while traveling over a fairly old slide runout. We skied terrain above 35 degrees and experienced sluffing around us. We skied the north facing couloir at the head of Owl Creek and had small wind slabs release as we skied for the top 150 or so feet of the couloir. The wind slabs ranged in thickness from 1 to 4 inches. They broke off in small chunks. There was still fantastic powder out there! You can see the couloir we skied as well as the avalanche debris that we felt the collapsing on in the photo below.
