In sintesi

Loose wet avalanche activity is tapering and avalanches are unlikely today. Use caution around and underneath extreme terrain facing the sun if you notice rollerballs, pinwheels or very saturated snow. Consider shadier aspects during the afternoon hours to avoid this problem entirely.

    Avalanche activity is likely tapering after four days of consistently warm, clear weather. A wet-loose avalanche remains a slim possiblity in isolated rocky terrain or steep sunny aspects in the late afternoon hours. Recent temperature inversions may also have prevented refreezing in isolated locations, allowing liquid water to continue to accumulate within the surface snow. Monitor how far you sink into the snow surface and the amount of melting happening throughout the day. If you are sinking more than three inches into the snow, avoid steep slopes facing the sun and be aware of any overhead hazards.

    Rock bands and cliffs can warm the surrounding snow and are common initiation zones for wet-loose avalanches like this. Give these features plenty of space, particularly later in the day.

Avalanche Discussion

Given the repetitive weather pattern avalanche conditions may seem straight forward, however, we are still wary of some of the crust layers in our snowpack. Concerning structure has been found about a foot down (the 1/3 crust) in the Elkhorns with two thin, melt-freeze crusts sandwiching a layer of weak snow grains. We have gotten unsettling, but inconsistent test results on this layer and have not seen any natural or human-triggered avalanches on this layer as of yet. If you plan to travel into upper elevations or consequential terrain, it is always prudent to take the time to dig and assess the snow structure where you are. If you find a consolidated slab of snow over a softer layer, it may be a reason to dial back your terrain choices. 

Help us paint the picture this week.  Please send us an observation!  Notable information includes what temperatures and snow surface textures you experience, the depth of any crusts, and the hardness of the snow above and below these crusts, as well as the amounts of snow you encounter at various elevations.
