MOUNT RAINIER NATIONAL PARK, Wash. — The National Park Service says the bodies of three climbers have been retrieved from a glacier on Mount Rainier in the same area where six went missing in May. A crew on a training flight this month spotted the bodies in an avalanche debris field after they were exposed by melting snow. Working with park rangers, NorthWest Helicopters used a remote-controlled grabbing device mounted from a 100-foot long line to lift the bodies off the Carbon Glacier. The area was considered too treacherous to reach on foot. There was no sign of the three other climbers. The Park Service says confirmation on the identities will come from the Pierce County medical examiner. Authorities believe the two guides and four climbers fell 3,300 feet as they took a technical route to the top of the volcano southeast of Seattle.
