Human-triggered avalanches are unlikely in most areas today. Continue to look out for unstable snow in isolated, wind-affected areas in very steep, rocky terrain and in sheltered, steep creek drainages. Low danger doesn’t mean no danger so continue to practice safe travel techniques.

It has been ten days since snow fell in western Wyoming. The snowpack continues to settle slowly with surface hoar and near surface facets continuing to develop. The day before yesterday, a party in Death Canyon triggered a wind slab in a small, but very steep and rocky terrain feature. Avalanches like this fit the definition of a low danger rating perfectly. It has been a couple of days since wind and available snow interacted to build some firm wind slabs but it is still possible to encounter a pocket in some shady, cold nook. This is the type of avalanche to be alert for when out enjoying these bluebird days, albeit in variable and often challenging surface conditions.

Deeper layers in the snowpack are far enough out of reach under strong snow that they can be considered dormant. It is highly unlikely that these layers will be an issue in the near term.

Remember the consequences of small avalanches triggered over terrain traps. The tragic accident that occurred in La Barge Creek is a reminder to remain vigilant in avalanche terrain at all times. Here is a link to the preliminary report.
