Comments

Size 2.5 Wet slab obs on W side of Elliot Pk (Passby Ck) . This area has strong PM solar, and slab initially appears to have been a thin storm slab, that ran 30m then stepped down to the Nov crust. This is a windward, shallow, and scoured start zone, in steep rocky terrain. Likely occurred with Sundays warmth and intense radiation. This is the first step down failure I have noted in the area this spring, and could become an increasing problem when we get some nice weather, with strong solar and increasing daytime and overnight temperatures penetrating deeper in the snowpack.
