MOUNT SHASTA, Calif. — Rescuers brought 10 climbers to safety from Mount Shasta over the weekend in separate incidents, and at least two of those who were rescued remained hospitalized Tuesday.

The climbers are recovering from injuries that include fractured ribs and a collapsed lung, said Eric White, a climbing ranger for Shasta-Trinity National Forest. At least one person fell hundreds of feet down the 14,179-foot volcano and others were hit by melting ice.

The Siskiyou County Sheriff's Office said seven people were injured Saturday and four more Sunday. White says most were evacuated by helicopter and snowmobile, and an 11th injured person was able to leave without being rescued.

"It was an unprecedented event," White said.

The names and conditions of all the injured were not immediately released, but one person was in serious condition, according to the California Highway Patrol.

Another was in stable condition at Mercy Medical Center Mt. Shasta, and six others were discharged, according to spokeswoman Joyce Zwanziger. At least two patients were admitted to Mercy Medical Center Redding.

White said warming weather led to falling ice chunks as large as beach balls, and the snow on the mountain is smooth and firm and the wind fast, making it difficult to maintain traction.
