Avalanche Activity

The last observed activity was from around the end of January. Observations found areas of D1-D2 natural windslab and storm slab avalanches on specific terrain that was wind loaded or cross-loaded, between 2500-5000ft. Some wind slabs were sliding on low-angle slopes as low as 25 degrees, and appeared to be sliding on a buried surface hoar layer 10-30cm deep. Distribution of these avalanches was limited to wind loaded areas that had been protected from strong N/NW winds.

Weather

We're in for a long period of very nice weather. Skies will be clear, winds should be light out of the north, and mountain temperatures reaching the 20's during the day. Our next chance at a storm looks to be Sunday night, but it will likely miss us.

Additional Information

If you get out riding, please send in an observation!

Do a rescue practice with your partners. Always carry a beacon, shovel, and probe, and KNOW HOW TO USE THEM.

Practice good risk management, which means only expose one person at a time to slopes 30 degrees and steeper, make group communication and unanimous decision making a priority, and choose your terrain wisely: eliminating unnecessary exposure and planning out your safe zones and escape routes.
