Kernpunkte

Dangerous avalanche conditions exist. Human triggered avalanches up to 2.5 feet deep are likely in steep terrain above 7,500’. Danger will be highest on wind-loaded slopes, but any steep sheltered slope on the north half of the compass is suspect. Remotely triggering avalanches on steep slopes above you while travelling on connected low-angle terrain is possible. Give steep and consequential terrain a wide margin today as the snowpack adjusts to the recent storm.

    Weak snow is buried 1-2 feet below the surface. Triggering an avalanche large enough to bury a person is likely in very steep, shaded terrain above 7,500’. Recent snow is stressing weak layers and increasing the likelihood of a rider triggering a large avalanche. Steep, sheltered, northerly-facing slopes harbor the weakest snow and are the most dangerous. Other aspects could also produce avalanches and should not be ruled out. You may not see signs of instability like recent avalanches or hear collapsing before triggering a large avalanche. Remotely triggering a large avalanche above you on steep slopes is a real possibility like this example from Togwotee yesterday. Give yourself a margin of safety around steep slopes today.

    This recent avalanche from the Snake River Range is a good example of the persistent slab problem that we are dealing with. Note the wide propagation across slope.

    Over the last 3 days, the Salt and Wyoming Ranges have received up to 14 inches of snow. Moderate south and west winds have redistributed this snow on multiple aspects and formed wind slabs up to 2.5 feet deep. These slabs may be sensitive to the weight of a rider in steep, wind-loaded terrain today. Wind slabs have the potential to step down to deeper weak layers in very steep terrain on the north half of the compass. If this occurs, avalanches may break deeper and wider than expected.

Avalanche Discussion

Carefully evaluate steep slopes on the north half of the compass between 8,000’ and 9,500’. Weak snow left from the January drought remains buried in these locations. Dig down to see if you can find sugary, faceted snow. Perhaps more of a concern are areas of buried surface hoar with a similar distribution. Regardless, recent human-triggered avalanches in surrounding zones have shown that the persistent slab problem exists in these locations. In areas where the wind slab problem overlaps the persistent slab problem, expect an increased likelihood of triggering, and give yourself a margin of safety around steep slopes.
