You'll find good, fast, re-crystallized powder conditions today in many areas. But, some drifting occurred in the last few days and it is continuing in exposed terrain at upper elevations. The fine powder from last week has settled substantially and it is re-crystallized, fast, and quite sugary in places. Frost or feathery surface hoar is evident on the surface and is widespread in sheltered terrain and at lower and mid elevations. You'll find sun crusts on south facing slopes and rather weak and crumbly crusts on more east or west facing slopes hit by the sun at a less direct angle.
A severe temperature inversion is in place over northern Utah, with sub-zero temperature readings down here in Cache Valley and almost 40 degrees warmer on the mountain summits. The Tony Grove Snotel at 8400' reports a balmy 29 degrees this morning, 47 inches of total snow, and 82% of average water content for the date. The CSI Logan Peak weather station reports northwest winds, with wind speeds averaging in the lower teens, and I'm reading 29 degrees at the 9700' station.
We've noticed evidence of natural avalanche activity in some areas that occurred during last week's storm. My party triggered a sizable loose dry sluff up in Deep Canyon in the Wellsville Mountain Wilderness on Monday, and an observer reported triggering similar loose snow suffs yesterday in the southern Wellsville Range. I was able to crack out a couple small wind slabs while skiing along a sub-ridge in south Wood Camp yesterday. These were around 6" deep and maybe 10' wide, but I could certainly see potential for larger triggered wind slabs in more wind exposed terrain.
