Place: Grand Teton National Park, Mt Moran, Sickle Couloir
State: WY
Country: USA
Fatalities: 2
Summary: 4 ski mountaineers caught, 2 injured, 1 killed

On Sunday morning 4 ski mountaineers were caught in a small avalanche as they climbed the rugged Sickle Couloir on the northeast face of Mt Moran. Three of the four were swept about 500 feet over rocks and ice. One skier was killed, another suffered life-threatening injuries that required a helicopter rescue. Sadly, this skier succumbed to his injuries late Tuesday evening (5/20) in an Idaho Hospital. Of the other two skiers one suffered relatively minor injuries and one was only brushed by the avalanche and not injured.

The Tetons have had a wet and cool May. From Friday to Sunday morning the Jackson Hole Ski Area (about 17 miles south-southwest of Mt Moran) received 10" of new snow at 9580'. The summit of Mt Moran is 12,605'. Before the skiers started climbing the couloir they found a large pile of fresh avalanche debris indicating the path had already produced a full track avalanche.
