Logan

Drifting by strong winds created areas with MODERATE avalanche danger, primarily in exposed upper-elevation terrain. Heightened avalanche conditions exist at all elevations on recently drifted slopes steeper than 30°, where wind slabs formed on a persistent weak layer of faceted surface snow, and people could trigger 1-2 feet thick slab avalanches of wind-drifted snow. The danger is LOW in sheltered mid and lower-elevation terrain in the backcountry.

Evaluate snow and terrain carefully, and reconsider your route if it takes you onto or under steep slopes with recent deposits of wind-drifted snow.

Urgent battery replacement is required for anyone who received batteries from one of our participating "Batteries for Beacons" shops. Please review the replacement notice for "Batteries for Beacons" on our blog, HERE. Batteries distributed through our "Batteries for Beacons" program this year are of inadequate length. We apologize and will provide you with new batteries.

• On Friday, a snowboarder unintentionally triggered and was caught and carried by a hard wind slab avalanche. Luckily, they were uninjured, and we are grateful they were willing to share their story. HERE

Saturday's east wind really messed up the nice powder in the backcountry. On Logan Peak, wind speeds averaged near 25 MPH, with gusts in the 40s MPH all day. Snow was carried far downslope towards Cache Valley, and there are recently formed wind slabs in unusual or unexpected places at all elevations. The snow surface has taken a beating, and finding consistent areas with soft snow is challenging. Wind-jacked snow was observed on slopes facing all directions and at all elevations yesterday. Riding is a bit bumpy, and the snow is solid and supportable on most slopes, but you never feel sure whether or not the crust will break and catch a ski.

Subject to an extreme temperature gradient caused by a prolonged dry spell with cold temperatures and clear nights, the snow near the surface has become very weak and faceted. Strong winds blowing from all directions last week and over the weekend built stiff slabs on this layer of weak snow, and some of these could be balanced, awaiting someone to come along and trigger them. Watch for shooting cracks indicating instability, and avoid hollow-sounding or rounded pillows of snow. East winds are unusual, so look for and avoid wind slabs in unusual places.
