A 56-year-old man was injured after falling about 15 feet at the Black Cliffs near the U.S. Highway 21 Diversion Dam, according to the Boise Fire Department.
The man was climbing with a partner when he fell.
The individual he was climbing with called dispatch to report the injury.
When crews found him, they loaded him onto a stretcher and took about a half hour to get him to Life Flight where he was flown to St. Alphonsus for treatment.
Capt. Randy Barnack of the Boise Fire Department emphasized that activities such as rock climbing should be done with a partner in case accidents occur.
"Don't climb alone. This would have been completely different if he would have been solo. But he had a partner. The partner recognized the problem and called for help and luckily he got some help," Capt. Barnack explained. "If he was by himself it could have been hours before anyone realized there was a problem. "
The man who fell had approximately 30 years of climbing experience, officials say.
