(Timberline Lodge, OR) -- A climber was rescued from Mount Hood on Saturday after falling 700-feet. The Clackamas County Sheriff's office says the climber fell on the Old Chute Route, which is very steep. Two off-duty military medics were also climbing the mountain and witnessed the fall. They treated the person until help arrived. An Oregon National Guard Helicopter landed on a portion of the Hogsback and flew the injured climber off the mountain. The rescue took around six hours. The injured climber is identified as 55-year-old Chris Zwierzyski, of Arizona.
