OREGON CITY, Ore. (AP) - A rock climber's body has been recovered after a large amount of rock fell on him from above in an Oregon City park.

Officials with Clackamas Fire District 1 say authorities were called to a rescue in the area of Promontory Park Thursday morning by a friend of the climber who reported the man missing and then searched the park, finding the man unconscious.

Authorities say Clackamas Fire crews arrived and found the climber deceased.

Fire officials say the climber was hanging from his rope system about 30 feet up the face of a rock wall and that rock from above had fallen and presumably caused the climber's injuries.

It wasn't known if the climber was wearing a helmet.

Fire officials say the rocks in the park are unstable and shouldn't be climbed.
