A party above us ascending SW Bryant Peak towards Bryant Col triggered a small wind slab, around 4" thick. The slide channeled through a gully and stopped before reaching us. Party above us reported that they observed cracking and hollow sounding snow in that area. Subsequent travel didn't reveal any slides or cracks/hollow sounds. Weather observations: there was a strong wind (NE) at the Bryant col around 3pm, with gusts estimated up to 30 mph. During the day we observed significant wind transport at the Chair Peak east ridge crest (SW) around 10am and at Melakwa Pass (S) around 1pm. Mix of sun and clouds, sunny when slide happened.
