Weather

Beautiful day. Temps in the 20s near TL and 30s at pass level. Light winds.

Snowpack

In general, snowdepths are still less than 1m. Observed numerous moderate collapses on all aspects near and below TL, but didn't feel they indicated widespread instability. Mid-pack facets are worrisome, but need additional slab overburden for an avalanche cycle. Surface hoar in favored locations, near surface facets elsewhere.

Avalanche

Activity from the Wednesday storm was very isolated. No additional activity observed during the last two days with improved visibility.
