Danger Rose Tutorial

Pockets of Considerable dot an otherwise MODERATE landscape in the northwest through east facing terrain above roughly 9500’. Natural avalanches are a thing of the past, but human triggered avalanches 1-2’ deep remain possible. Soft and hard slab avalanches may still be triggered at a distance (even above you) and are likely to propagate more widely than before. Traumatic injury in the threadbare coverage remains severe – it’s just as likely to get dragged into rocks, stumps, and trees as it is to be buried in a slide.

The danger is LOW on slopes less than 30 degrees in steepness with nothing steeper above.


The moist and breezy northwesterly flow is starting to lose some steam and dry out. Skies are mostly clear, temperatures are in the teens, and the Mt. Ogden winds are a more reasonable 15-20mph with gusts to 30. Should be a pleasant day in the hills. Yesterday’s stronger winds resulted in some wind damage and drifting, but creativity and tolerance should be enough to piece things together. Low angle protected terrain in the shady aspects should again be the ticket for today.


Few reports filtered in yesterday, though we did hear of continued collapsing of the weekend’s storm snow onto the old weaker snow beneath. Control work in the Cottonwoods continues to produce avalanches 1-3’ deep in the steep upper elevation northerly through easterly terrain. Symptomatic of the snow structure, many of these slides went on to pull out pockets in adjacent terrain.

      Over the next 24 hours.

Time tends to heal all wounds, but it’s not time yet. Perhaps most have circled the wagons, stopped and taken stock of the madness, tragedy, and avalanche conditions from Sunday.

The storm snow from the weekend is starting to gain some strength and the interface between it and the weak sugary faceted snow now buried 1-2’ down is starting to slowly adjust. In other words, while human triggering was likely over the last few days, it is slightly less so now. There are fewer signs of the instability, but the structure remains. It’ll be easy to be lured out onto the slope. Give it some time.


      Over the next 24 hours.

The stronger northwesterly winds likely produced some stiffer drifts along the high lee (primarily with an easterly component) terrain which may crack out with provocation. Anything that starts to move may step down into the older October/November snow below.


It’s a day of transition. We’ll have clear skies, light to moderate backing winds to the west, and 8000’ and 10,000’ temps in the upper 20s and teens, respectively. Ahead of what looks to be a potent, if somewhat short-lived, storm late Friday into Saturday, we can expect rapidly warming temperatures and escalating southwesterly winds tomorrow into Friday. The cold front crashes through by late afternoon and we can expect upwards of a foot of snow, with perhaps a bit more in areas favored by a northwest to westerly flow. The Lake Effect looks favorable at this time to add some to the snow totals – stay tuned.


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.
