HEADS UP.... the landscape is different this morning and it's game on-
At mid and upper elevations, especially on steep wind drifted slopes facing the north half of the compass the avalanche danger is HIGH. HUMAN TRIGGERED AVALANCHES ARE VERY LIKELY AND NATURAL AVALANCHES LIKELY. TRAVEL IN AVALANCHE TERRAIN IS NOT RECOMMENDED.

Special Announcements
We are very proud to introduce our new website for the 2018-19 winter season. This will provide an easier and cleaner way to view all of the snow and avalanche information that you've come to rely on. We are quite happy with how the new website performs on mobile devices as well. We think you'll find the desktop or laptop experience pleasant as well. We are still tying up some loose ends so bear with us.
Weather and Snow
The first wave of the big storm arrived last night, delivering about 6"-8" of dense, heavy snow across the range. Temperatures are mild and in the low 30's. West-southwest winds are cranking 40-60 mph along the ridges. The next wave of snow with much colder air is on our doorstep and should slam into the region in the next couple of hours. Heavy snow is expected and we should be able to stack up an additional 8"-10" by late morning.
Our main man Ted Scroggin has been out and about, stomping around Bald Mountain Pass and in Whitney Basin since early November. He reports a thin, yet layered snowpack with about 18" of snow on the ground on upper elevation, north facing slopes.
This is exactly the type of terrain that's gonna be sketchy as today's storm evolves.
Wanna avoid avalanche danger this weekend? Of course you do and it's easy. Simply steer clear of any mid or upper elevation slope that has pre-existing, early season snow.
Your exit strategy is to swing around to south facing terrain which has no old snow and you can ride without the worry of avalanches breaking to weak snow near the ground.
Recent Avalanches
Yesterday, backcountry travelers were finding widespread collapsing, shooting cracks, and easily triggered soft slabs on road cuts and steep, leeward slopes facing the north half of the compass.

Description
Overnight, west and southwest winds began cranking into the 40's and 50's along the ridges. In addition, last nights dose of dense heavy snow and rising temperatures are all conspiring against our shallow, fragile snowpack. And while there's a little bit of structure and a couple of crusts holding things together, quite frankly, I don't think this setup is much of a match for the big weekend storm. Now I'm not going to geek out on you and talk snow science or theory. What I do want to tell you is this... it's gonna get sketchy today and any avalanche triggered will quickly get out of hand, revealing a myraid of hidden obstacles like stumps and rocks that will easily ruin your day or end your season. Bulls-eye terrain and the slopes you want to avoid are located in mid and upper elevations, particularly those facing the north half of the compass where the snowpack is weak and sugary.
Mirror Lake Highway and Wolf Creek Pass are still open, but just 'cause you can see your rig parked on Bald Mountain Pass or near Wolf Creek, doesn't mean the terrain you're choosing to ride is good to go.
Remember- this is the time of year where most of us get tricked thinking there isn't enough snow to avalanche. However, this is also the type of setup when most close calls and accidents occur. If you are getting out and about, be prepared for your own self rescue. Wear and know how to use an avalanche beacon, shovel, and probe.
Ted was out and about near Murdock Bowl and found the snow structure setup in the image above, noting he couldn't even isolate the column of snow before it failed to the weak, midpack facets.... spooky. Click HERE to see his take on things and view a short viddy.

Description
Winds are all over the map, creating widespread drifts sensitive to our additional weight, even at lower elevations. Be on the lookout for and avoid steep wind drifted slopes especially if they look fat, rounded, or pillowy.
Additional Information
Snow showers end this evening and skies begin clearing. Temperatures crash into the teens overnight. A rapid warming trend is expected early next week as a ridge builds in.

If you're getting out and about, please let me know what you're seeing especially if you see or trigger and avalanche. I can be reached at [email protected] or 801-231-2170
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.
