Park rangers have stopped their active ground searches near the Ozette Loop Trail for Bryan Lee Johnston.
Park spokeswoman Barb Maynes told The Peninsula Daily News they are now focusing on speaking with people who may have seen Johnston in or around Olympic National Park.
At least 50 park rangers, in addition to search teams from Clallam, Grays Harbor and Pierce counties, have searched for Johnston since Wednesday and have turned up no clues.
Family members reported Johnston missing Wednesday after he had not returned from a planned two- or three-day hike on the Ozette Loop Trail.
He left home Aug. 22.
