Kernpunkte

At upper elevations in the wind zone, a CONSIDERABLE avalanche danger exists on all quadrants of the compass and human triggered avalanches are PROBABLE onsteep, wind drifted slopes. Any avalanche triggered may break to weak snow near the ground, creating a larger avalanche than will quickly get out of hand.

Not as widespread, you'll find older drifts reactive to our additional weight in mid elevation terrain as well, where a MODERATE avalanche danger exists. Human triggered avalanches are POSSIBLE on steep, wind drifted leeward slopes.

Where to ride?

Wind sheltered, low and mid elevation terrain and big open meadows are the place to be where you'll find great riding and generally LOW avalanche danger. In terrain with these characteristics human triggered avalanches are unlikely.

    A great observation from long time observer, avy educator, and guide extraordinaire, Cody Hughes viddy shows fresh drifts are reactive to the additional weight of a person. Cody's most excellent observation from yesterday's travels found here.

    Yesterday's strong southwesterly winds had no problem whipping up our recent New Year storm snow, creating drifts, sensitive to our additional weight. Most prevalent on upper elevation leeward slopes, I wouldn't be too surprised to find a fresh drift or two cross-loaded onto terrain features like chutes and gullies. Of course, your best bet for avoidance is to simply steer clear of any fat, rounded piece of snow, especially if it sounds hollow like a drum. In addition, look for shooting cracks in the snow which is a sure sign of unstable conditions.

    A wild card added to the mix of avalanche problems now includes steep, upper elevation slopes, facing the south half of the compass, where strong snow rests on weak snow underneath a post Christmas suncrust. The slide above triggered Friday near Tower Mountain paints a complicated snowpack stability picture.

    The good new is... we've got a great start to the season and our pack is looking encouragingly solid, especially where it's deep and nearing 4' of total settled snow. The bad news.... no matter how you cut it, we've got persistent weaknesses on all aspects of the compass, particularly in upper elevation terrain. And the bottom line is... anything persistent in our pack is tricky, can take long periods of time to heal, and snowpit stability tests often suggest false "green light" conditions. So that means, you can ride some slopes and be good to go, while others just wait for us to roll along and knock the legs out from underneath. And here's the danger... once initiated, avalanches have a distinct possibility of breaking deeper and wider than you might expect.

    Meanwhile.... we've been very focused on upper elevation, shady slopes, but I was curious how shallow snow looks at lower elevations. My travels yesterday steered me towards lower and mid elevation north facing terrain and the viddy above illustrates how that early season structure is looking. A great exit strategy is to meadow skip in low angle terrain where you can have a blast!

Recent Activity

Friday, a group of riders triggered a large avalanche, on a very steep, heavily wind loaded, upper elevation, southeast facing slope near Strawberry Reservoir. Reported as 5' deep and 800' wide and failing on weak snow near the ground, this large slide broke as the rider was climbing the slope. Fortunately he was about 20 feet from the crownline, grabbed some throttle, and was able to punch it to the ridge, narrowly escaping the slide. The big heads up here is... this is a sunny slope, where we generally head to when there's elevated avy danger, expecting to avoid weak snow issues usually found on shady slopes. However, strong northwesterly winds earlier this week, coupled with nearly a foot of midweek storm snow helped connect this very stout slab. And this all rests on lower density snow from the Christmas storm.... strong snow on weak snow. All we need to do is roll along and knock the legs out from underneath. Stoked everyone is OK and deeply appreciate the great reporting from this crew of riders!

Snow and Weather

Currently-

Skies are clear and current temperatures register in the teens. No new snow has fallen in the past 24 hours and southwest winds blow 15-25 mph along the high ridges. Yesterday's powder punishing winds damaged our big open bowls and high alpine terrain. But lose a little elevation, head to wind sheltered slopes and you'll be rewarded with soft, surfy snow. The range has excellent early season coverage with total snow depths averaging close to 4' of settled snow.

Above is a 24 hour run from Windy Peak, illustrating yesterday's strong ridgetop winds.

For today-

Expect increasing clouds with snow developing later in the day. Not a big storm, but enough new snow for a shallow reset. Southwest winds ramp up this morning and blow in the 40's and 50's along the high ridges. High temperatures climb into the 20's and overnight lows dip into the teens.
