All of the above snow conditions were found out there. The best skiing and riding conditions were to be found on mellow protected slopes in the trees and out of the wind.

The wind surely got its hands on any snow that was available for transport. Minor collapsing in isolated areas skinning through mellow terrain.

Decreasing Danger
Problem #1 Comments
Definitely becoming more difficult to awake the avalanche dragon, but the possibility is still there. Weak layers are still evident in the midpack that could prove to be problematic.

Wind Slab

Increasing Danger
Problem #2 Comments
For the lack of snow we have, the wind continued to find snow to transport throughout the day. Manageable avalanche problem, but needs to be matched with the proper terrain.

North facing slopes display the little amount of snow, at least it is snow though.
