Forecast for the Uintas Area Mountains

Tuesday morning, December 29, 2020
Heads up... the southern half of the range, which received more storm snow and wind, offers a deceptively trickier avalanche danger-
In the wind zone, at and above treeline, you'll find pockets of CONSIDERABLE avalanche danger. Human triggered avalanches are LIKELY on steep, wind drifted slopes. Steep terrain facing the north half of the compass, and particularly slopes with a westerly component to its aspect are most suspect and should be avoided.
Mid elevations offer MODERATE avalanche danger on steep slopes facing the north half of the compass and human triggered avalanches are POSSIBLE.
In either case, once triggered, today's avalanches may break deeper and wider than you might expect.
LOW avalanche danger is found on mid and low elevation slopes, particularly those facing south, but snow cover is super thin.

Special Announcements
Thanks for sharing your snow, your slope, and your stoke... well played!
A big shout out, high fives, and air hugs to the crew I met on Christmas Eve at Wolf Creek who not only brought an amazingly positive energy to the day.... you showed how to avoid avalanche danger by choosing the right terrain. In the image above, everyone opted to avoid the avalanche dragon on the steep, shady slope yet still had a great day on low angle terrain facing the south half of the compass, riding shallow pow, with their families, in the sun.
You know the program... roadside attractions are still an easy grab and just 'cause you can see it from the car doesn't mean it's safe or you're good to go. And remember, our front-line health care workers are maxed out. So, let's collectively think about our decisions and the consequences that may have on others.
Thanks to the generous support of our local resorts, Ski Utah, and Backcountry, discount lift tickets are now available. Support the UAC while you ski at the resorts this season. Tickets are available here.
Drew Hardesty has an excellent new blog post.

Weather and Snow
Nowcast-
Yesterday's storm clipped the North Slope, delivering just an inch or two of snow, whilst benefiting the south half of the range with a much needed 4" of medium density snow. Under a big, bright, beautiful moon, skies are clearing and temperatures crashed into the single digits overnight, where they sit this morning. A thin coat of white paint goes a long way and riding conditions slowly improve, but with total snow depths averaging just about two feet in depth the Uinta's are still quite thin and travel is sorta limited to road rides and grassy slopes.
Forecast-
A stray snow shower lingers over the area and clouds thin out, yielding to mostly sunny skies as the day progresses. Northeasterly winds blow in the 20's and 30's along the high peaks and temperatures crack into the teens and low 20's. Under clear skies, tonight's lows crater into negative territory.
Futurecast-
A break in the action is slated for Wednesday and another weak storm is on tap for Thursday.

Recent Avalanches
Tyler St. Jeor gave me the heads up about an unusual slide triggered by a skier in the Timber Lakes zone yesterday. Not huge, nor particularly connected, but occurred on a northwest facing, mid elevation slope... 30 degrees in steepness. The low angle nature of the slide is a big red flag, illustrating the the extremely weak characteristics of our current snowpack.
Sidenote... Tyler is the real deal and contributes an enormous energy to the community as an ace UAC observer, snowmobile educator extraordinaire with Backcountry Institute, Wasatch SAR member, and Canyons patroller.
In addition, Chad was in Murdock Basin Sunday and has a great trip report here. Both of us experienced lots of collapses and shooting cracks over the weekend, but no significant new avalanche activity to report.

Avalanche Problem #1
Persistent Weak Layer

Description
Persistent weak layers... they're are a pain in the pack because they linger for long periods of time. And recent history tells us that every time we stack up additional snow or windload to our fragile snowpack, we see human triggered avalanches. And here's the deal... nothing's changed with our problem child because we're not getting plastered with big storms, or the dense, heavy snow needed to help add a thick, insulating coat to our snowpack. As a matter of fact, we're getting teased along with just enough snow to keep the weak layers teetering on the edge. Now here's the setup. The snowpack foundation mirrors an upside-down cake... think, stronger snow on weaker snow. This type of layering leads to tricky avalanche conditions because there's not widespread, in-your-face, natural avalanche activity. Rather, our snowpack needs a trigger like us to roll along and knock the legs out from underneath. And yes... we can trigger slides from a distance or from adjacent slopes, and this is the type of avalanche dragon where we can pull the entire log pile down on top of us, even if we're playing on low angle terrain. All we need is to be connected to steep terrain above us. And once triggered, today's avalanches may break wider and deeper than you might expect.
But you don't have to ride blind... so, tweak small test slopes like the one in the image above, looking for and listening to signs of unstable snow like whoomping sounds and sudden collapses of the snowpack or shooting cracks in front of your skis, board, or sled. And of course the biggest clue of all... recent avalanches, especially on the same types of slopes you wanna ride on.
Avalanche Problem #2
Wind Drifted Snow

Description
About as calm as it gets for a place named Windy Peak... above is a 24 hour data grab from Monday through early this morning.
Winds weren't a big game changer with this storm, but as we all know, the Uinta's are a big place and I bet if you were looking for a fresh wind drift... you could find one. Problem is, today's drifts are hidden under a little fresh snow, making them harder to detect. So... let's think like the snowpack and consider the most likely place is on the leeward side of upper elevation ridges. But, since winds were all over the compass late in the weekend, terrain features like chutes and gullies may be cross-loaded and should be considered suspect. In either case, it's an easy and mostly manageable avalanche problem to avoid by simply steering clear of any fat, rounded piece of snow, particularly if it sounds hollow like a drum. And remember... our snowpack is super shallow and triggering even a small slide can take you for a body-bruising ride through rocks and stumps barely hidden under the thin snowpack.
Additional Information
Two weeks ago, I rolled up to a fresh avalanche and found Utah Snowmobile Association president, Cal Taylor, investigating the slide and performing a mock rescue with his riding partner Mike Davis. In the video above, Cal has some sage advice for our riding community.
I'll update this forecast by 7:00 AM tomorrow, Wednesday December 30th.
