            *** 1 FATAL ***
            A report of a skier who failed to return
            home by 500 pm MST was received by Summit
            County Dispatch on the evening of the event
            3/7. A search and rescue operation was
            started that evening, and crews found
            evidence of a recent slide, but due to
            reportedly extremely hazardous conditions
            the crews had to wait to continue the search
            until the following morning. Search and
            rescue crew ultimately found the body of a
            deceased 51 year old man at 1049 am MST,
            with a determination that he had been caught
            in the avalanche on a steep northeast aspect
            of Hoyt Peaks NE bowl. A forecaster with the
            Utah Avalanche Center stated that warm and
            strong spring sunshine may have been a
            contributing factor to reactivate multiple
            weak layers buried beneath the current
            snowpack. A nearby SNOTEL, Beaver Divide,
            recorded 1.1 inches of water from the start
            of the event through 500 pm MST 3/7, which
            at a reasonable 13 to 1 snow to liquid ratio
            would equate to 14.3 inches of snow. The
            closest SNOTEL, Redden Mine LWR, through the
            same time period recorded 2.5 inches of
            water, or at the same ratio approximately
            32.5 inches of snow. A storm in mid February
            produced nearly 4 inches of water, or
            approximately 36 inches of heavy dense snow,
            along with heavy winds. Exact time of
            avalanche is estimated.
