Danger Rose Tutorial

Although most slopes are stable, there is a localized MODERATE danger for the old hard wind drifts, mostly in above tree-line terrain. There is also an isolated MODERATE danger for triggering a deep slab avalanche mostly on north through east facing terrain at the mid and upper elevations. 



We are in the clutches of the dreaded January doldrums with high pressure building in.  This means smog in the valley and warm sunshine in the mountains.  It also means we clog our lungs and shorten our life if we stay in the valleys so we go into the fresh air of the mountains where we can watch the creation of weak layers on the snow surface in preparation for being overloaded by future slabs that may shorten our lives even more quickly. Temperatures continue to warm as the high pressure builds in.  Ridge top temperatures have risen to 25 degrees with a chilly 15 degrees down in the mountain basin bottoms.  Ridge top winds are very light.  The snow surface above tree line has lots of wind damage but there is still some creamy, dry, recrystallized snow on the north through east facing slopes.



People have been jumping into all the big, scary lines and not triggering avalanches.  For the Wasatch Range, you can follow some of these exploits at the various blogs such as StraightChuter, WowWasatch or Telemark Tips.  We’re lucky to have so many volunteer stability testers.  Explosive control work at the Cottonwood Canyon resorts yesterday pulled one deeper slab with a large charge on a southeast facing slope at 10,500 feet that had recent wind loading.  This was 3 feet deep by 120 feet wide.


      Over the next 24 hours.


Although we have a mostly low avalanche danger there are certainly some places where you can get into trouble if you are looking for it—or not looking, which is a bigger problem.

The first problem is lingering, stubborn, wind slabs left over from the strong winds a few days ago.  Although the stored elastic energy has drained out of most of them, there may be some that you can still trigger.  As always, be suspicious of steep slopes with recent deposits of wind drifted snow.


      Over the next 24 hours.

Our old friend, the deeply-buried layer of weak, sugary, faceted snow still lurks in some areas, especially in steep, shallow, rocky areas.    Although most of these weak layers are buried so deep that they are hard to trigger in the Wasatch Range, they are much more sensitive in the Uinta Mountains where the snowpack is shallower and weaker.  Be sure to check the Uinta advisory before heading there.


Warm, sunny and calm up high; cold and smoggy down low.  And it’s going to stay that way until about next Thursday when some moisture drifts in from the southwest.  Ridge top temperatures will be in the mid to upper 30’s with light wind.  Temperatures down at 8,000’ will get into the mid 40’s.



The last of the Brighton Discount tickets have been reduced to $45, with all proceeds going to the Friends of the Utah Avalanche Center. 

So check it out.  

The Friends of the Utah Avalanche Center is hosting a Level 2 avalanche class in February which is now open for registration by going to the Black Diamond retail store.  More information is HERE.  

Tickets are now available for the annual Backcountry Awareness Dinner on February 13th, with registration through the Snowbird Renaissance Center.

Beacon training parks are up and running!  There is one at Snowbasin, one on the Park City side at the top of Canyon’s gondola, one in Little Cottonwood near the Snowbird parking structure on the bypass road, and in Big Cottonwood a training  park is at the west end of Solitude's lower parking lot.
