HEADS UP.... it's a day of rising avalanche hazard.
At mid and upper elevations, especially on steep wind drifted slopes facing the north half of the compass the avalanche danger is CONSIDERABLE. HUMAN TRIGGERED AVALANCHES ARE LIKELY AND NATURAL AVALANCHES ARE POSSIBLE.

Weather and Snow
Yesterday's storm delivered a solid 6" of medium density snow across the range and a trailing band of moisture laid down and additional one or two inches overnight. Temperatures are in the mid 20's and west-southwest winds blow 15-25 mph along the ridges. Winds ramp up ahead of the next system slated to impact the region later today. It looks like a good shot of snow, water, and wind and we can expect periods of high density snow with increasing west and southwest winds gusting into the 60's along the high ridges by days end. Strong winds are forecast tonight ahead of the next cold front, expected to pass through the region Saturday morning. Snow density will be high again tonight, decreasing significantly Saturday behind the cold front. I expect we should see snow totals in the 12"-18" range by this time Saturday morning. Temperatures crash into the single digits with snow showers ending mid Saturday evening. A significant warming trend is forecast early next week with a ridge building in.

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 the holiday 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
Shallow, yet very touchy soft slabs were reported on road cuts and steep, leeward slopes facing the north half of the compass.

Description
Strong winds, dense heavy snow, and rising temperatures all conspire 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.
Both Ted and Michael J found similar snow structure on opposite sides of the range. Michael's pit is from Wolf Creek on Nov. 21st... more details here. Ted's ob is from Hayden Pass on Nov. 17th... more details here.

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.
