A solo skier exited the boundary of the Loveland Ski Area and climbed to a saddle at 11800 feet. He descended an east aspect into moderate terrain with a steep convex roll mid-path. The skier triggered an avalanche at the convex roll, was caught in the slide, and fully buried when the debris came to rest on a bench in the terrain. A snowboarder riding nearby saw the fresh avalanche,assembled his slpit board to ski with no skins, and skated to the accident site. He began searching with his avalanche rescue beacon, but found no signal. He began a visual search of the site for clues. He discovered the end of a ski pole protruding from the debris downhill of the victims ski tracks. The snowboarder dug down the shaft of the ski pole and found the victims hand in the strap of the pole grip. He continued to dig and was able to extricate the skier. Burial time was estimated at 10 minutes.
