GOVERNMENT CAMP (AP) — A rescue operation is under way on Mount Hood for a man, apparently a climber who reported leg and ankle injuries.

Steve Rollins of Portland Mountain Rescue says the man has a cell phone and that rescuers are using signals from it to pinpoint his location.

He’s believed to be in an area at 10,500 feet on the common southern climbing route. Rollins says he called for help late Wednesday morning.

He said rescuers were headed up the mountain and that the climber appeared in no imminent danger. But he says bad weather is possible.

The mountain is 11,239 feet, Oregon’s highest. It is a frequent source of trouble, especially for climbers who underestimate it or climb late in the season when the snow softens and glacial crevasses widen.
