Persistent slabs lie upon a base of weak, faceted snow on a variety of aspects above 7,500 feet. Skiers and riders traveling into steep, avalanche terrain could trigger these slabs with depths up to two feet. Persistent slabs pose a significant threat to backcountry users as they can remain unstable for days or weeks. Previous tracks are also not an indication of stability.
