Lo esencial

Triggering an avalanche large enough to bury, injure, or kill you is possible above 7500 feet. Deep, weak layers buried 2-4 feet remain a threat on steep, shady slopes, especially around thin rocky areas. Shallow drifts along ridges and in exposed areas could avalanche and send you into consequential terrain. Use caution in these areas and evaluate the snowpack on steep slopes carefully. Avoid wind-affected, steep and rocky slopes at upper elevations.

    Weak layers of snow formed in December remain buried 2-4 feet at the base of the snowpack. It remains possible to trigger a large avalanche on this weak layer. Steep slopes above 7500 feet remain suspect. Triggering an avalanche is most likely in thin areas around rocks or in exposed areas where the wind has drifted snow. The problem is worse on shady aspects on the north half of the compass, but with a big enough trigger, any steep slope with weak, sugary snow at the ground remains suspect. Whumphing and shooting cracks are usually absent with large hard slab avalanches.  Give yourself plenty of room around steep slopes, and remember that you could trigger a steep slope just by riding underneath it.

    Recent warm temperatures have created generally safe conditions below 7500’.

    Moderate northerly winds have built 1-2 foot thick slabs at upper elevations. These slabs will be located along ridges and around exposed rocky features and gullies. Look for pillows and stiff drifts, and watch for shooting cracks or collapses. These small slabs could still knock you off your feet, so consider the terrain below you and the consequence of even a small avalanche. Avoid this problem by staying off exposed steep slopes where you see signs of wind-affected snow.

Avalanche Discussion

It’s going to be another great day to get out with good visibility. Sunny skies and recent snow tend to get me excited. Don’t let your guard down and get sucked onto steep shady slopes. Keep your head on a swivel and anticipate thin spots in the snowpack where a larger trigger, like a snowmobile, could set off a slide. Look above you and make sure there is not a looming cornice that might break off and trigger a large avalanche. Give the snowpack time to adjust to the long stretch of storms that wrapped up only yesterday. Check your beacons and travel one at a time around steeper slopes.
