A 75-year-old man from The Dalles who became lost Thursday while hiking in the Laurence Lake area in the Upper Hood River Valley was located Sunday afternoon in good condition.  The Hood River County Sheriff’s Office says David Bullock was able to find his way back to the west end of Laurence Lake and flag down a fisherman.  Bullock had become separated from his wife while on a day hike Thursday afternoon when he wanted to go check out a rock formation.  Bullock told the Sheriff’s officers on Sunday that when he came back down from the rock formation he became lost, and he went back to the rocks then down another direction.  Bullock reported hearing a search helicopter on Friday, but could not get to a location to be seen.  Sunday morning he came to a point where he could see the lake, allowing him to hike down to it.  Bullock survived on stream water and built a shelter to keep himself warm at night.  He was reunited with his family at Providence Hood River Memorial Hospital, where he was taken for evaluation.
