Tetons

Overnight strong west-southwest winds have added an additional load to upper elevation starting zones. Soft slabs up to four feet in depth exist at the mid and upper elevations. Two days ago a four foot deep slab avalanche was triggered by a snowboarder on a steep shaded aspect beneath Drews Slide in the Green River Drainage south of the Jackson Hole Mountain Resort. Similar events could be triggered by humans today. At the lower elevations isolated pockets of slab up to 2 feet in depth could be human triggered in steep wind loaded avalanche starting zones.
