A 26-year-old man died Sunday afternoon after he crashed into a tree while snowboarding at the Eldora Mountain Resort in Boulder County.

The Boulder County Sheriff’s Office said witnesses called 911 to report the collision at 3:50 p.m. Sunday.

The snowboarder was riding down the Jolly Jug Run when he rode into the tree — the same trail on which two expert teenaged skiers were injured the day before after they ran into each other.

Bystanders performed CPR on the snowboarder as they waited for emergency officials to arrive. The snowboarder was wearing a helmet at the time of the collision, deputies said. 

A medical helicopter and ground rescue crews were deployed, reaching the man by 3:55 p.m.

Officials transported him to the first aid room with emergency medical personnel; however, he succumbed to his injuries and was pronounced dead at 4:40 p.m., deputies said. 

The identity of the victim will be released by the Boulder County Coroner’s Office after his family has been notified.

Agencies that assisted in the incident included the Boulder County Sheriff’s Office, American Medical Response, Nederland Fire Rescue and Northern Colorado Medevac.
