No new natural avalanche activity.
Snowpack Summary
Not a whole lot of change when it doesnt snow. Widespread hard slabs in alpine terrain overlying weak facetted crystals and depth hoar. At treeline there are two layers of concern, the Jan 16th SH layer which was found up to 2300m and is now down 20-30cm in the snowpack and the Dec 13th Crust which is down 40-50cm with a weak layer of facetted grains overlying it. Generally, still looks like early season out there even though its the middle of the season...
