Route & General Observations
Drove through Summit Lake between 3pm and 4pm. Observed significant flagging/blowing snow along ridge tops on both sides of the road. NW winds were primarily loading Eastern and Southern slopes. Recent natural avalanche activity was reported earlier in the week on Southern and Eastern aspects following a similar strong wind event on 2/27 -2/28. It was difficult to know if all of the natural activity observed today (3/2) was from earlier in the week.
Active wind loading and numerous recent large avalanches:
Several Naturals on E - NE aspects of Colorado Peak- all D2's (starting zone just below ridge tops)
Natural D2 on SW aspect of Tenderfoot (starting zone 2500')
Natural D1.5 wind slabs on S aspect of Manitoba - its possible that these were older than this week... unconfirmed.
Strong NW winds
Temps - single digits F near ridges and teens near road
Blowing and drifting snow along road in some places and on Summit Lake
