Notes
On Sunday, one snowmobiler in a group of four was caught and killed in a small avalanche on Ski Hill at the south end of Lionhead Ridge. He was on a 45-degree slope when it released and partially buried him against a tree. The slide was only 4"-11" deep, 75 feet wide and ran 300 feet vertical. His head was a foot under the snow. The avalanche was not witnessed and the victim was buried an estimated 15-25 minutes before he was uncovered. Rescue efforts were not successful. The group was familiar with the area and had rescue gear. The shallow, steep slide ended in trees, a terrain trap . Our deepest condolences go out to the family and friends of the rider.
