Injured Climber Rescued From Black Lake Area

Rangers were notified of the activation of a spot tracker device just after noon last Saturday. Shortly thereafter, they received a 911 call reporting a climbing accident near Black Lake.

Fifty-year-old Jason Brooks was solo climbing (unroped) when he reportedly took a tumbling fall of about 100 feet onto soft snow. The fall was witnessed by visitors who were at Black Lake, which is about five-and-a-half miles from the Glacier Gorge Trailhead. Rangers arrived on scene about two-and-a-half hours from the initial call.

Brooks suffered numerous injuries but was ambulatory and with assistance from rangers was able to move down to an area where an air ambulance was able to land. Flight for Life transported him to Medical Center of the Rockies at 4:15 p.m.

Fortunately, weather conditions and the location were conducive to assistance from a helicopter. Teams of Rocky Mountain National Park search and rescue personnel, assisted by Larimer County Search and Rescue and Rocky Mountain Rescue, were preparing for the possibility of a lengthy rescue operation.
