A 25-year-old man was rescued after he injured his leg during a fall from the First Flatiron in Boulder, according to Boulder County Sheriff’s Office.

Officials say the man was scrambling, which is a type of rock climbing without the use of rope or other technical climbing gear, on the backside of the First Flatiron and fell approximately 20 feet about 10:15 AM. A group of hikers in the area provided first aid before rescue crews arrived, the Sheriff’s Office said.

The man was not able to walk out of the area due to injury of his lower leg. Rescuers brought him out in a litter, which is a type of bed used by search and rescue crews, back to the trailhead where he was loaded into an ambulance and transported to a nearby hospital. The rescue took approximately four hours.
