Red Flags Comment
<p>Found lots of weak snow in our pit on E-facing 9000' slope, but it's under a solid 4-5" layer of dense storm snow and a few crusts that appear to be holding everything together. The Tues/Wed storm snow came in wet and warm and has capped everything with rain crusts, frozen/rime graupel crusts, and soft but thick graupel snow. We observed no red flags today. </p>

We found excellent corn snow on our exit, starting at 8400' all the way back down to the highway.

Instability Comment
<p>Old facets from January/February are still intact and still producing propagation. (ECTP24 at old/new interface)</p>

It's hard to describe the surface snow right now, as it varies widely by elevation and aspect. We observed bullerproof crusted snow bw 7300-8000' on our ascent. From 8000-8700, the surface snow was rimed and felt like styrofoam. 8700-9000' was wind-ravaged and very firm. Lots of large graupel visible from Tues/Wed warm storm.
