Snow Characteristics Comments
Great snow conditions but difficult trail breaking. Snow was generally not wind affected on most aspects traveled (W,NW). Southerly aspects received sun and could potentially have a slight crust tomorrow. Snow surface was already weakening with up to 4mm surface hoar in some spots.

Problem #1 Comments
New snow easily sluffing in steeper terrain. We observed two relatively small natural loose snow slides on Murdock. See photos below. The other one was a bit larger and ran from the top.

Problem #2 Comments
We didn't dig and look at it but it is still there. Gobblers avalanche today is good verification that it is still a factor, particularly in thinner snowpack areas.
Today we looked at evidence of an avalanche from the mid-January storm cycle that ran full track. This slide took out some trees and flagged others, opening up the skiing a little bit. We haven't seen this path run this far previously.
In this path, there is a long relatively low angle run out which makes it seems like you might be out of the way but this avalanche demonstrates otherwise. Some of the damage to trees is the result of the avalanche air blast.
