DENVER (KDVR) — The Grand County Sheriff’s Office reported that a man who attempted to clear Highway 40 in a “high-risk skiing stunt” died on April 9.

According to the agency, the communications center received a 911 call at about 3 p.m. on Tuesday, April 9, reporting a skiing accident on U.S. Highway 40 near milepost 241.5, which is just west of the Berthoud Pass Summit. The caller reported a 21-year-old man was unconscious and not breathing, and that a bystander had initiated CPR.

When emergency responders arrived on scene, they found the man was deceased and the Grand County Coroner’s Office was asked to respond to the area.

Investigators found that the victim was attempting to “perform a high-risk skiing stunt by trying to clear the width of Highway 40.” The man was unsuccessful, authorities said, and unfortunately lacked the necessary speed and distance, causing him to land on the highway pavement.

Authorities said the victim was wearing a helmet and other protective gear during the stunt.

Investigators closed U.S. Highway 40 to traffic in both directions while processing the scene and maintaining the victim’s privacy. The man’s identity and cause and manner of death will be released “when appropriate” by the Grand County Coroner’s Office.
