Washington man goes missing while climbing Oregon's Mount Hood

A 26-year-old man from Washington state went missing in Oregon while climbing one of the most treacherous mountains in the U.S., authorities said Friday.

The Clackamas County Sheriff's Office said the climber and his friend summited Mount Hood from the Timberline Lodge on Thursday, but they got separated in "very foggy" weather. The missing climber's name was not released. 

Once officers were notified at about 4 p.m. Thursday, the sheriff's office said its search and rescue team attempted to find the missing man using cellphone signals, working into the night to locate him.
