Accident Summary

PRELIMINARY REPORT

A group of three snowboarders using snowmobiles to access the backcountry from Vail Pass were involved in a large avalanche. Two riders were caught. One was washed into a stand of trees, and was killed. He likely died from his injuries. The other rode out or most of the way out of the debris. Other touring groups in the area helped with the first response. US Forest Service, Eagle and Summit County Sheriff's offices, Vail Mountain Rescue Group, and Summit County Rescue Group responded to the accident. CAIC staff will visit the site on April 19th. We will report more information as it becomes available.

The deep, persistent-slab avalanche is described at 10' deep and close to 300' wide. It broke trees 3-5" in diameter. It released on a north aspect in a near-treeline area.
