New snow and strong varying winds at all elevations have increased the avalanche hazard. At 
the upper elevations new soft slabs to two feet in depth exist on steep avalanche prone 
slopes. These slabs could be easily human triggered today and have the potential to pull out 
deeper layers of recent snow in rocky areas and near cliff edges. At the mid elevations 
pockets of slab could also be triggered one to two feet in depth in wind loaded areas. At 
the low elevations small pockets of wind blown snow lie on hard crusts in steep terrain. A 
skier was caught and buried by a small slide near Superbowl in the Mail Cabin area of Teton 
Pass yesterday afternoon.
