A man was intoxicated when he became lost in an out-of-bounds area at Aspen Mountain in Colorado Saturday night, according to Pitkin County Sheriff’s Office.

Reports of a lost and possibly injured snowboarder were made about 7 PM in an out-of-bounds area of Ruthie’s Run, which is a blue-rated ski trail on Aspen Mountain.

The snowboarder was identified as a 39-year-old from Aspen, the Sheriff’s Office said.

Rescue crews were able to contact the snowboarder with help from the Air Force Rescue Coordination Center and determined he was in the Keno Gulch off of Aspen Mountain in the Castle Creek Valley. Crews entered the field about 8:05 PM and became close enough to the lost snowboarder to hear his voice about 9:37 PM.

The snowboarder was “cold and tired,” but uninjured, the Sheriff’s Office said.

By about 10:05 PM, rescuers began the downhill trek with the man, however it was reported that due to his intoxication and the very rugged terrain, the rescue mission was a slow process. They reached the bottom of the valley behind the Aspen Country Day School at 11:13 PM, and by 11:40 PM all Ski Patrol members made it out of the field.

Backcountry travel during winter can be especially dangerous, officials warn.

“Doing so alone and unprepared while under the influence of alcohol is a recipe for disaster,” the Sheriff’s Office said in a news release.
