Four hours after the avalanche, a dog belonging to the ski patrol identified what turned out to be the place where the missing man was buried. His body was under 2 to 3 feet of snow. Nevada County Sheriff\'s Sgt. Bob Jakobs said the identity of the man would not be released until family had been notified.
