Several other climbers were stranded on Oregon's tallest peak after heavy snow created risky climbing conditions on Oregon's tallest mountain.
A male mountain climber was pronounced dead upon arrival after being airlifted to Legacy Emanuel Medical Center, according to the Clackamas County Sheriff.
Earlier on Tuesday, the Clackamas County Sheriff's office said one group of four hikers was stranded, one of the climbers had been injured, and another climber had fallen.
Rescuers made it up to the climbers at about 4:40 p.m. Tuesday at 10,500-foot elevation and assessed them before starting down the mountain. An additional three climbers were making their way down the mountain without assistance.
"The ice conditions up there were really challenging", said Steve Rollins with the Portland Mountain Rescue.
More than half a dozen people had been climbing near Mount Hood's peak when a climber fell about 1,000ft (305m) said Sergeant Brian Jensen, spokesman for Clackamas County sheriff's office.
Mount Hood, notorious for loose ice and rocks in warm weather, is a popular climbing site that has seen dozens of accidents and fatalities over the years.
Russian Olympic curler becomes Winter Olympics photo (and crowd) favorite
Russian curler Anastasia Bryzgalova is sending the internet into a frenzy - as much for what she's done off the ice as on it. The Russians' win on Tuesday gives them the distinction of nabbing the first-ever Olympic medal in mixed doubles curling .
The other climbers began signaling for help and performed CPR on the victim for nearly two hours.
"They were kind of pinned down, sketched out and didn't want to come down on their own", said Dave Clark, a volunteer rescue leader with Portland Mountain Rescue. Other climbers are providing aid as rescuers try to reach the scene.
Deputies said that person's injuries were not life-threatening, but while the group was in a safe location, moving down from that spot was considered hazardous.
Russell Gubele of Mountain Wave Search and Rescue said Tuesday that he is unable to release information about the climber's condition.
At least one has died after falling several hundred feet on the cliff.
The stuck climbers were on or near the Hogsback area near the summit of the 11,240-foot (3,429-meter) mountain east of Portland. Thousands climb it each year, mostly in the spring.
