Danger Rose Tutorial

The avalanche danger is Level 2 (Moderate) for wet sluffs on steep sunny slopes, east through south through west, and on low to mid elevation shady slopes if the snow becomes damp.

there are pockets of Level 2 (Moderate) avalanche danger on most upper elevation slopes where a larger avalanche could be triggered in isolated places.


The mountains are off to a very warm start this morning, with temperatures at most elevations in the upper twenties to mid thirties. Only the canyon bottoms are cool, near 20. The winds are from the northwest and generally less than 15 mph, with only a few of the highest peaks gusting to 30. On sheltered, shady slopes the turning and riding is excellent, “loud”, (and getting louder) surface hoar and near surface facets.


there are no recent reports of avalanches from the Ogden area mountains.

In upper Little Cottonwood yesterday, explosives released large slides on steep, upper elevation northerly facing terrain, breaking out 2 to 3’ deep and up to 500’ wide, all failing on the surface hoar layer buried below the crust.

Down on Cascade Ridge, in the Provo area mountains, something a little different is happening. A slide was remotely triggered, failing on surface hoar above the rain crust, on an east facing slope at 10,000’, a foot deep by 200’ wide, running 1500’ vertical.

And finally, both dry and wet sluffs occurred yesterday on steep slopes.


      Over the next 24 hours.

No recent avalanches in the Ogden area mountians have been triggered on the buried surface hoar or the facets below the crust. However, the weak structure does exist, especially at the highest elevations, so the below information is still of interest in the Ogden area mountains.

Once again, the snowpack is sending mixed messages – many steep lines have been skied, boarded and ridden without incident over the past few days, yet in the exact right spot or with a big enough trigger, large slides can be released, failing on the buried surface hoar (rose of recent surface hoar avalanches). The weak structure is widespread throughout the range – both a buried surface hoar layer and facets below the ice crust. The crust and facets are continuing to weaken in many areas. On most slopes, there is just not enough of a load yet, but in a few isolated places all it would take is the additional weight of a person to trigger a slide.

If you are using snow pit tests for stability analysis, you need to selectively look for weakest areas to dig your pits, because that most represents where you could trigger a slide. When you chose to get into steep terrain, look carefully at the consequences of a mistake – a ride will be much more serious if you go over a cliff, are strained through trees, or dumped into a gully.


      Over the next 10 hours.

A much more widespread, but more predictable issue today will be wet avalanches. With such a warm start to the day, the snow on steep, sunny slopes facing east through south through west will heat rapidly as the sun moves across the sky. Wet sluffs will be easy to trigger, and natural avalanches are possible. Once the snow starts moving, any damp sluff could entrain snow down to crust, so slides could run faster and farther than expected, with big debris piles. In addition, the snow on the shady, northerly facing slopes at the low and mid elevations could also become damp, and human triggered sluffs will be possible.


It is going to be a sizzler in the mountains today, with 8,000’ temperatures warming into the mid 40’s and high ridge line temperatures warming into the mid 30’s. Winds will be variable and very light, less than 10 mph, at most elevations, with only the highest peaks and ridges averaging 15 to 25, with occasional gusts to 35. The high pressure will persist through Saturday. Weak disturbances in a northerly flow will bring cooler air and a few inches of snow late Sunday through Tuesday.


If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
