Comments
We found good coverage and mostly stable summer corn or firn snow in the Tony Grove Area. Exceptions are large overhanging cornices along the main Bear River Crest, and we noticed a fairly large recent natural cornice fall avalanche in Cornice Ridge Bowl. The dust on the snow surface has caused sun cups to develop in lower angled and sunny terrain, but we found areas with very nice smooth and silky conditions.

Comments
It is possible to drive to within about a mile of the lake. Remember that this is a shared use area, with plenty of hikers, skiers, sledders, dogs, and kids, so remember to continue following social distancing guidelines, practice safe backcountry travel protocols, please be polite, and keep your speed down.
