Mammoth Basin Avalanche Advisory

Tuesday, April 24, 2018 - 6:11am

Loose wet avalanches will be the primary concern for the forecast period. Time your day to be off of steep sunny slopes before they become unsupportable. Pinwheels rolling down the hill, small wet sluffs originating from rocky areas or exposed vegetation, and boot-top penetration into wet snow are direct signs that triggering loose wet avalanches is becoming increasingly possible.

If you are out in the mountains early enough to hit good corn by late morning you may encounter firm snow conditions before the surface melts. Ski and boot crampons, an ice ax, and helmet can help reduce your vulnerability in a slide-for-life scenario where a simple slip and fall could have higher consequences on steep alpine terrain.
