DICKERSON RUN, Pa. (AP) - Police say a man has died after he fell at a popular rock climbing site in southwestern Pennsylvania.

Authorities were called to Coll's Cove in Dunbar Township around 2:20 p.m. Sunday after the man fell between 40 and 60 feet. He was pronounced dead shortly after.

Officials say the victim was climbing in a group and rappelling when he fell. It's unclear what caused the fall.

Investigators didn't immediately identify the victim. An autopsy will be performed Monday.
