Comments

The Skyline has a pockety avalanche problem, where avalanches can break into the buried weak layer of faceted snow near the ground. These types of avalanches will be unmanageable and could be triggered from a distance. Best to avoid steepE, N, NE, NW facing slopes steeper than 30 degrees in steepness. Slopes that face the southern half of the compass are generally a safer bet.

Great riding conditions with a supportable base, but don't let that trick you into thinking slopes are stable. The main problem is the extremely weak snow that is now buried 2-4 feet deep in places. Its a house of cards out there right now, its just waiting to come crashing down. The avalanches will be large enough to bury or seriously injury you.

Boondocking in the rock free meadows is the safest bet for now. We avoided all avalanche terrain today, and will do the same for tomorrow's outing. This is a patience game, and right now we need to have some patience and leave the hills alone.
