Snow Characteristics Comments

Mixed bag in my travels from 6,700' to 9,100.  Wind exposed areas were scoured and loaded.  Many of the cornices I dropped yesterday were reformed.  Yesterdays skin track was blown in or away.

Still finding settled snow in wind protected areas ranging from settled powder to weakening snow over a crust.

Low elevation areas are damp and/or crusty depending on exposure.

Rapid Warming
Red Flags Comments
I walked through a lot of wind loaded areas today without any reaction or red flags in wind slabs. Only some limited minor, non-shooting cracks. Low elevation areas got warm enough to be of concern on solar aspects.

Problem #1 Comments

Although I did not see any real red flags I still adjusted my route to avoid steep wind loaded areas and did not follow my normal route.

Moderate hazard below 9,000', I would imagine more loading occurred at higher elevations.

Problem #2 Comments

Wet slabs will be a possibility with increasing temps.
