Utah Avalanche Center

Ton of new snow, upside down, very difficult trail breaking, triggered a few very large whumpfs in low angle terrain.

Small intermittent shrubs at base of pit breaking up basal facet layer. No rain here. 50 - 75 cm layer may have been weak layer for yesterday's avalanches at higher elevations. Lacking a slab here, no wind load, not enough new snow.

Probably rained on 18 cm to 30 cm layer before it switched to snow. Also thinking pack was out of inversion at times, with warm air temperatures. Temp estimated.

Large HS avalanche, triggered by snowmobilers

Surface snow may be the greatest concern when we get more snow. The presence of surface hoar tells us that faceting is occuring. The "knee" in the temp profile also shows diurnal recyrstallization is likely occurring.

Stability tests didn't break. The snowpack just crumbled beneath the shovel. Faceted snowpack for sure, but not too bad for Uintas.

Looks like the bowl above snow pit avalanched during east wind event on 12/31.
