SUMMIT COUNTY (KUTV) -- SUMMIT COUNTY (KUTV) -- Summit County sheriffs have released the identity of the man killed in a Summit County avalanche Saturday.
49-year-old Jason Lyman of Mona was killed after being buried while snowmobiling near Humpy Peak.
At 1:20 p.m. Saturday, the Summit County Sheriffs received an SOS signal in the East Fork of the Chalk Creek area of Summit County.
That signal indicated a snowmobiler, later identified as Lyman, was buried in an avalanche and a helicopter was dispatched to rescue him.
Lyman was buried in the avalanche for 30 to 40 minutes before two friends were able to dig him out.
"After two friends dug him out, they began CPR and continued to administer lifesaving efforts for more than 40 minutes until a Utah DPS helicopter was able to get to the patient," Summit County Sheriffs said in a news release. "[Lyman] was transported by the DPS helicopter to an Evanston, Wyoming hospital where he died. No one else was injured in the avalanche. The avalanche is estimated to be 500-600 feet wide and 4-10 feet deep at the toe."
