PRELIMINARY REPORT: A group of three backcountry tourers were involved in an avalanche near Red Peak in the Gore Range, west of the town of Silverthorne. The group ascended to the east summit of Red Peak (point 12,885'). They began their descent of a couloir on the north side of point 12,885'. During the descent they triggered a small avalanche. The avalanche swept one of the riders through the couloir and to the valley below.
Summit County Rescue Group and the Summit County Sheriff's Office responded. CAIC staff will visit the site and we'll publish more information as it become available.
