Mammoth Basin Avalanche Advisory

Saturday, March 24, 2018 - 6:44am

The complexity of the wind slab problem near and above treeline will create CONSIDERABLE avalanche danger today. Recent, large wind slabs may be gaining strength, but new sensitive wind slabs may form by this afternoon – especially North of Mammoth. Cautious route finding and conservative decision making is required to asses and manage the complexity. MODERATE danger exists below treeline where it is increasingly unlikely to trigger a storm slab or the deep persistent slabs, but if triggered the resulting slide could be very large.
