Today, we skied near the wilderness boundary north of Round Lake. On a wind-loaded test slope at the top of our second ski run, we were able to get recent drifts to crack, but not avalanche. Slightly further down on a steep roll the second skier in our group triggered a small wind slab avalanche. This avalanche was 15-20' wide, 8" deep, and ran for about 30-40 vertical feet. The skier easily skied away from the slide and was not caught. 

Winds remained mostly calm but increased by the end of the day. Snowfall through the day was enough to partially cover our morning tracks and we found 2" of snow on our snowmobiles at the end of the day.
