One dead in eastern Summit County avalanche

A 49-year-old man from Mona died Saturday in an avalanche in the eastern part of Summit County, according to the Summit County Sheriff’s Office.

Sheriff’s Lt. Andrew Wright said the avalanche occurred in the East Fork of the Chalk Creek area, east of Coalville. Dispatchers received an SOS signal from an avalanche beacon around 1:20 p.m. Avalanche beacons allow backcountry users to send a GPS signal to emergency responders in the event of a slide.

According to Wright, the man, later identified as Jason Lyman, was snowmobiling with two friends when the avalanche was triggered. He was buried in snow for 30 to 40 minutes before his friends were able to dig him out. The friends performed CPR on Lyman until a Utah Department of Public Safety helicopter arrived to transport him to a hospital in Evanston, Wyoming. Lyman was pronounced dead at the hospital.

No one else was injured in the avalanche, which was estimated at between 500 and 600 feet wide and 4 to 10 feet deep.

Summit County Search and Rescue also responded to the incident.
