Generally safe avalanche conditions. Small avalanches are possible in isolated areas or extreme terrain. Remember that risk is inherent in mountain travel.
We are transitioning back to intermittent updates. The next update will be on Wednesday.

Special Announcements
Most ski areas are now closed to uphill travel as they open or prepare to open for winter operations. Resort uphill travel policies can be found HERE.
Alta Ski Area has closed the Summer Road and access to Catherine's for lift area operations. Grizzly Gulch remains open. The Highway to Heaven above Twin Lakes is closed.
Weather and Snow
There is a beautiful book, written by the French aviator Antoine de St. Exupéry, called Wind, Sand, and Stars. Part of it details a time when his plane crashed in the Libyan desert. I think it was 1935. With little water between them, it wasn’t long until he and his navigator began experiencing visual and auditory hallucinations. Mirages appeared on the landscape, though they were always just out of reach. It’s a little like looking at the weather models these days…
Skies are clear. With a building ridge of high pressure, we'll have sunny skies, light northwest winds and warming temperatures through the weekend and into the early part of the week. Tranquil. A storm appears on the horizon for mid-week, but I suspect it will pass to the northeast of us. The weather models hint at a pattern change by the end of the month.

In the meantime, backcountry travel is easy and riding conditions remain quite good for mid-November. Some wind and sun damage exist in the alpine and on the solar aspects, respectively, but sheltered aspects hold soft recrystallized snow. Snow depths are 3-4' in the upper reaches of the Cottonwoods and 2-3' along the Park City ridgeline. Ogden snow depths are 2-3' while Provo trails with only 1-2' of snow on the ground.
While it seems like nothing is going on, there is in fact A LOT going on in the snowpack. The cold, (mostly) calm, and clear skies have not only promoted weakening and faceting in the upper layers of the snowpack, but these atmospheric conditions have been conducive for surface hoar (wintertime equivalent of dew) deposition on many slopes. I use the word deposition with care: whereas faceting and weakening take place within the snowpack, surface hoar is deposited onto the snow surface. It all makes for soft, turnable snow now, but facets and surface hoar often cause trouble with avalanches down the road. We'll see.

From Ogden to the central Wasatch to the Provo mountains, we have received a number of excellent observations. You can find them HERE. Please keep these excellent reports coming.
Recent Avalanches
A skier-triggered avalanche was reported from Wednesday in Upper Red Pine. The avalanche was on a northeast aspect at 10,500' and involved a small pocket of wind-drifted snow 8" deep and 70' wide where the rider was caught and carried for 350'.

Description
Normal Caution is advised. A couple of things to have on the radar:
  • Loose dry sluffing is possible in steep shady terrain.
  • Pockets of wind drifted snow may be found in the high alpine terrain.
