Quick report

Good stability, likely decreasing on steep sunny slopes in the afternoon.

Clear, calm, warm day. Didn't observe any wind transport. Maybe a few plumes on distant peaks, but tough to say.

Snowpack

Snow cover is minimal below 3,000ft, with areas of bare ground and open creeks. Above 4,000ft, found recent dry snow over the 1/31 crust. Snow depths increased exponentially with elevation. At 6,250ft on the ridge between Whiteface and Gate creeks, found 5-8cm of recent, dry snow over the 1/31 crust. The crust was supportive to boots. Rime and recent snow caked the trees on the ridge.

On SE-SW aspects, the sun was warming surfaces and even melting the old 1/31 crust below 4,500ft. We didn't observe wet snow instability, but I could imagine it was happening in other terrain with more available soft surface snow.

We didn't observe wet loose avalanches in the terrain we traveled, but I imagine these occured on steep slopes with enough available snow. One older avalanche was reported by another party on the north side of McLeod Mtn. A larger, D2.5, wet slab from the late January rain event.
