Danger Rose Tutorial

A MODERATE avalanche danger still exists for triggering a wind slab or a cornice in the upper elevation terrain. MODERATE means human triggered avalanches are possible. Most importantly, keep in mind that the danger for wet avalanches will be on the rise and could reach CONSIDERABLE if things get warm enough. If natural wet activity does occur the slides have a potential to be quite large. Stay clear of sunny runnout zones as things heat up. Out of wind affected terrain, the majority of the terrain has a LOW danger this morning.


While most people, including myself, found the newest snow to be quite stable in most locations, there were two pockets reported of skier triggered slabs. One was 4 to 8” deep on a steep mid slope rollover in Mineral Fork and one was up to a foot deep on another very steep easterly facing slope in Mill B South. It sounds as if both were the result of a period of winds stirring up the surface snow. Most other people found the recent drifts to be stubborn and tickled a number of them without incident. As far as wet activity, there was very little as the cold air mass and scattered clouds won out over the direct solar radiation. There were a couple of heat initiated avalanches that did spill onto the Big Cottonwood Highway from steep road banks that were large enough to get a plow out to clear them. Higher in elevation there wasn’t even much rollerball activity.


      Over the next 10 hours.

The biggest problem for today will be wet avalanches if things heat up enough as the day goes on. Temperatures will get slightly warmer today then on Friday but we may see some scattered clouds again. I’m not totally convinced that we’ll see a widespread natural wet cycle but the large amount of fresh cold snow and direct spring time solar radiation dictates that we keep a close eye on the snow today for heat initiated avalanches.


      Over the next 24 hours.

Some good sized fresh cornices have been reported from the recent winds which should be avoided today. It is not uncommon for fresh cornices to be sensitive as temperatures warm. Also keep in mind that these winds did transport snow into fresh drifts. With another 24 hours of settlement now, these fresh drifts will be more stubborn but you should keep them in mind if you’re attempting to get into very steep upper elevation terrain. Fairly good stability on a sunny Saturday will lure many people into the high country today. After seeing lots of signs of stability as you travel today it will be easy to overlook pockets that may release and take a person for a ride.


We’ll have scattered clouds again today with temperatures a little warmer getting into the mid to upper 30s at 8000 feet and around 30 along the ridges. We’ll have light to moderate northwest wind speeds with some stronger gusts at the most exposed locations. Another storm is expected for later on Sunday which could produce another good shot of snow in northwest flow.

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 toward the Tombstone lift, 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.
