Kernpunkte

A cold storm came through yesterday and is on it's way out this morning. It brought 3" of new snow to Summit Lake with some northerly ridgetop wind. Despite the small amount of new snow, a person could still trigger an avalanche on a wind slab up to 2' deep above treeline. Look for softer snow and safer riding options at lower elevations in wind protected areas.

    Recent avalanches: There was a small human-triggered avalanche on the north side of Tenderfoot on Sunday. It looked like it occurred on a steep wind loaded roll.

    There are a variety of wind slabs within treeline and above today that should be reactive especially this morning. Fresh small wind slabs 6" to 1' deep above 2,500' will be the most likely problem to encounter today. There is also a chance we could trigger a larger avalanche up to 2' deep on an older wind slab. This is because there is weak snow sitting under those old wind slabs that still have potential to release. We don't know exactly how sensitive those older wind slabs are today, but we do know where they exist. 

    They form just below ridgelines, on steep rolls (like the one that was triggered on Tenderfoot Sunday), and in cross-loaded gullies. Ease into terrain today and look for opportunities to test a small wind loaded slope to see how reactive it might be. Cracks that shoot out from you mean the snow needs more time to adjust to the new weight. Old wind slabs sometimes don't give any feedback so an escape and rescue plan is good to have if we get surprised.

    Dry Loose Avalanches: There is now 5 or 6" of new snow since Friday sitting on some slick old surfaces. Dry loose avalanches should still be relatively small, but could be big enough to knock us off our feet or send us somewhere we don't want to go. Choose runouts that don't have obstacles and that fan out at the bottom.
