Weak, faceted snow persists at the base of the snow pack on northerly and shaded aspects above 9,000 feet. Skiers and riders have the potential to trigger slab avalanches on this layer with depths to three feet. Today's new snow and winds will increase the sensitivity of these persistent slabs to human triggers. Caution is advised as these slabs mail fail after a slope has been crossed several times.
