A 30-year-old man was killed while snowboarding outside of the ski area boundaries in Whistler, B.C., Sunday.

The Whistler resident was found face down and buried in snow in the heavily forested area known to locals as the "Khyber Pass."

He was found by a group of passing skiers, who dug him out of the snow and began performing CPR around 11:30 a.m.

Police, ski patrol and search and rescue workers were notified, and located the victim an hour later.

Members of the Whistler Ski Patrol continued CPR, but were unable to save the snowboarder.

RCMP Staff Sgt. Steve LeClair told ctvbc.ca that the victim had been snowboarding with a group of friends, but they became separated as they made their way through the trees.

"His friends were waiting for him further down the mountain," he said.

Police believe the snowboarder fell into a hole created by fallen trees and suffocated in the deep snow.

The victim's identity is being withheld until the next of kin are notified, but LeClair said that he was originally from outside of B.C.
