Observations

Tour’d up to skyline lake, down into the basin and up Tye Peak until we remote triggered a wind slab. Bailed the same way we came in. Fog/cloud cover all day, no substantial precipitation, no wind. Skiing conditions mostly consisted of 2-8 inches of heavy snow on top of the ice crust.
