Highlights

Generally safe avalanche conditions exist. Small wet snow instabilities may develop late in the day on steep slopes where solar input and radiative heating from rocks have softened surfaces. Travel early when conditions are most supportable, and move to mellower terrain if you observe mushy or punchy snow.

Mountaineering hazards include slide-for-life surfaces, rockfall, and strong winds aloft. Proficient use of crampons and ice axe is essential for safe travel.

    Recent observations indicate that wet loose snow is most likely to develop on steep (>35 degrees) slopes receiving direct solar input, specifically near or below large rock outcrops. In these areas, use boot penetration to assess surface supportability as you travel, and consider the consequences of being knocked off your feet and taking a sliding fall. If you observe signs that the upper snowpack is losing strength, such as greasy snow atop a firm crust or sinking into mushy snow past your ankles, seek mellower terrain. 

    Keep in mind that the most suspect slopes are often the ones offering the best riding conditions. Even small wet loose slides can be dangerous on long, sustained slopes with exposed rocks in the runout.

    Set yourself up for success by starting early, when surfaces are most supportable, and by identifying areas where wet snow instabilities may develop so you can avoid or manage them later in the day. Continue to give cornices a healthy distance when traveling both above and below them.

Avalanche Discussion

March is coming to a close, and so are the “spring-like” conditions. A refresh of snow is on the way for Mount Shasta and a well-earned reset to many heavily textured surfaces. As stormy weather returns, expect wind slabs to take center stage and avalanche danger to rise.

It has been a low-snow year for the Eddy Mountains. A recent helicopter snow survey highlights the below-average snow depths and coverage. Read the full observation HERE. Snow depths measure about five feet at the Old Ski Bowl (7,600 feet) on Mount Shasta and one to two feet at Bunny Flat (6,900 feet).

Mountaineers, the weather window is closing. While there have been a handful of successful summits so far, there have also been several rescues. April is right around the corner and is typically an excellent time for ski mountaineering and climbing.
