Summary: 1 snowmobiler caught buried and killed

A solo 16 year old snowmobiler was found deceased March 12th after

probing for three hours by the Teton County Search and Rescue group. The

slide occured in the Grove Creek drainage of the Big Holes-a small range

to the west of Victor and Driggs, Idaho and parallel to the Tetons. He

had been reported overdue the evening before by his family. It appeared

that he had triggered the slide that buried him when a cornice he was on

collapsed. He had no transceiver. The five days prior to the slide there

had been over three feet of snow with nearly three inches of water at

Jackson Hole Ski Resort twenty miles to the east. More details on the

slope, snowpack etc. When we get them.

More details

The slide path was just a couple miles from the victim's home. The path

was in a low, wind protected area and there was apparently no slab

involved. The slide origin (area that the "entrained"snow started from)

was about 50 meters by 50 meters and ran less than 60 meters vertically.

The debris piled deeply in a ravine and the snowmobile was on the

surface. The victim was not near the machine or in line with it in the

path and his head was approx. 90 cm deep. He was located by an avalanche

dog with handler from the Targhee Ski Resort. The Search and Rescue

group was from Teton County, Idaho.
