NORTH SISTER, OR -- Lane County Search and Rescue say it is too dangerous to continue the search for a Central Oregon man who fell at least 300 feet at North Sister. Joel Tranby’s family says he was climbing with his girlfriend Monday when he fell twice. He verbally responded after the first, but not after the second. She was rescued by a helicopter but he has not been found.

Authorities say the rough terrain is unstable with shifting boulders. They are analyzing high resolution photos taken by a drone for possible clues and will decide how to procede based on new information and resource availability.
