Rescuers race to reach four climbers after 18,200-foot fall on Denali

Four climbers fell near Denali Pass at about 18,200 feet on Alaska’s Mount Denali as rescuers try to reach them by helicopter amid variable weather; the seven-person team’s other members helped the injured and returned to high camp around 17,000 feet, and officials say this is an active rescue. Denali’s climbing season runs late April to mid-July, with about 516 climbers on the mountain as of Thursday, and two climbers from a separate incident were evacuated by helicopter the previous night.
