Quick report
Travel today up Neff's into Mill B North in Big Cottonwood Canyon. Strong winds from Wednesday have affected most aspects from low through the highest elevations. The wind drifts that formed over the past few days are generally 10-15 cms thick and vary from soft and breakable to pencil-hard, supportable wind slabs. We jumped on several test slopes and could only get cracking right around our skis, indicating the wind drifts were no longer reactive.
Generally Low avalanche danger on most slopes. However, I would avoid any steep, wind-loaded slope where triggering even a small wind slab could be consequential.
Photos of alpine terrain in Big Cottonwood. The second photo of Broads Fork shows a few small glide cracks, although they do not appear to be recent. With such a deep snowpack this season, glide avalanches have the potential to be quite large.
Snowpack
Widespread wind damage above 6,500' but still plenty of soft snow can be found in wind-sheltered terrain.
