None observed.
Observation: Turnagain
Location: Seattle Ridge
Skinned into the lower meadows of Seattle Ridge on the South end of Turngain Pass to look at a thinner snowpack that received wind loading yesterday. We made it to 2000′ just before the terrain become very steep above. The snow changed in this area from soft sastrugi and wind slabs to scoured and wind stripped above us.
