It feels like the snowpack is adjusting to the weekend storm and in most terrain across the range the pack is happy in its own skin. However, the Uinta's are a big zone and I bet there's still a surprise or two lurking out there today. Prime suspects include terrain that has already avalanched this year along with a vast majority of steep, shady slopes that have remained thin and shallow this winter. Terrain with these characteristics remains sketchy and should be considered guilty until proven otherwise. Sounds complicated, but the answer is easy. The way we manage unpredictable avalanche dragons is to simply avoid where they live. If you're looking for powder and safe riding, simply tone down your slope angles and avoid terrian with steep, wind drifted slopes hanging above you.
JG was in Weber Canyon yesterday and expeierinced a big, booming collapse. Here's his take on things-
"After collapsing a slope and getting propagation with medium effort on ECT's we decided to err on the side of caution and, for the most part, kept slope angles down and tried to minimize our exposure when we did get into steeper terrain. Just when I was starting to feel a little better about the persistent slab instability, signs today told me we're not quite out of the woods yet."
Sound advice from a very savvy backcountry rider with decades of experience in the Uinta's.
High, thin clouds drifted into the region late yesterday, but cleared overnight. Temperatures have risen into the low 20's. Along the high ridges southwest winds blow in the teens and mid 20's. Sunny slopes took on some heat yesterday and have a thin crust, but riding and turning conditions remain quite good, particularly on mid elevation, wind sheltered, shady slopes.

Ted was in Moffit Basin and found great riding along with an airshow provided by this flock of Cranes returning for their annual roost.

This avalanche in Humpy Creek was triggered by the 4th sledder on the slope. While a bit shaken, the rider was able to get off the moving piece of snow and came out on top. Reported as breaking 4'-6' deep and about 50' wide, it broke close to the ground. We'll take a look today and update the details.
Partly cloudy skies, light winds, and temperatures climbing into the upper 30's and low 40's are on tap today as high pressure remains in place over the region. A weak cold front may produce light snow showers late Friday, otherwise no big storms in sight.
Not particularly widespread, there might be a rogue drift or two that remains reactive to the additional weight of a rider. Stiff wind slabs are most prevalent on the leeward side of upper elevation ridges and around terrain features like chutes and gullies. Today's hard slabs are gonna be a bit stubborn, but once triggered, can potentially break deeper and wider than you might expect and are gonna pack a punch. You can ride safely today by looking for and avoiding fat, rounded pillows of snow, especially if they sound hollow like a drum.

It's also a good time to set up one of our very popular avalanche awareness classes. Reach out to me and I'll make it happen.
