Rescuers were called out at about 3 p.m. Sunday on a report of a man hiking in the area of the Third Flatiron in Chautauqua Park who was acting strangely, then fell about 200 feet down an embankment.

The man, Austin Stevens, admitted to taking hallucinogenic drugs prior to his hike, according to the Boulder County Sheriff’s Office. He sustained mild to moderate injuries in the fall and was taken to the hospital for treatment.

Deputies from the Boulder County Sheriff’s Office, rescuers from Rocky Mountain Rescue Group, rangers from the City of Boulder Mountain Parks and Open Space, the Boulder Fire Department and American Medical Response assisted in the rescue.
