We didn't really test any obvious drifts, and did not see any sign of natural activity. But, we noted significant surface drifting. I am concerned about drifted slopes where weak near surface facets formed during cold high pressure conditions in early February and only a couple inches accumulated incrementally since. Wind slabs developing on potentially persistent weak layers may remain sensitive to human triggering for a while, and hard slabs often allow you to get well out on them before releasing.. Because of these factors; stiffening and building on potential weak layers, the wind slabs are getting more unmanageable and dangerous.
