Observations

Skied out Cold Creek/FS 9070 to Twin Lakes (not fully frozen) then up to Windy Pass and up to ~5k' on the N slopes of Silver below the main bowl. Cloudy and cold with stout wind, light snow most of the day. Travel off of the road below ~4k' was slow (low tide, open creeks, downed trees, rain crust under a few inches of fresh snow). Enough fresh snow at higher elevations made travel easier. Several large cornices forming (from westerlies) on the NW ridge of Silver. Observed wind affected and blowing snow mostly ATL/NTL - one small whumpf in a pocket of wind deposited snow on final ascent to the 5k' bench. Skied 35-45 deg NE aspect glades with some dry loose slough.
