Rangers at Rocky Mountain National Park assisted in the weekend rescue of Colorado residents who had suffered injuries from a fall.

The National Park Service (NPS) said in a statement that it had been notified on Sunday of a 61-year-old Boulder man who had been injured in a significant tumbling fall on a snow couloir in the Ptarmigan Fingers area above Odessa Lake. 

However, it was later determined that a 59-year-old woman from Boulder also suffered injuries from a fall in the same area.  

Bystanders heard her calls for help and aided her, using satellite communication devices to contact the rangers.

To find the man, Northern Colorado Med Evac air ambulance assisted Rocky Mountain National Park Search and Rescue team members with air reconnaissance.

The park requested assistance from a Colorado National Guard helicopter from Buckley Air Force Base to extricate the man via a hoist operation – using a winch-operated cable – due to the location and severity of his injuries.

Rocky Mountain Rescue assisted with the helicopter hoist operations, which occurred at approximately 8 p.m. MT.
