MARBLEMOUNT, Wash. -- A hiker missing for more than three days in North Cascades National Park was found Sunday afternoon.

He walked to the trailhead on his own.

National Park spokeswoman Kerry Olson said Mark Albrecht was cold and hungry but otherwise unhurt.

The 22-year-old, who had recently moved to Everett from Indiana, had a permit to camp in the Cascade Pass area Monday and Tuesday nights.

Albrecht told KIRO TV News in an interview following his rescue that he became disoriented when he encountered fog on Wednesday morning as he descended from Sahale Glacier camp.

Realizing that he was lost by mid-morning Wednesday, he pitched his tent to await help.

On Sunday morning, he made a successful attempt to find his way down a creek drainage to the Cascade River Road and to the rescue crews stationed at the Eldorado parking area.

The search began when he did not call his parents to say he got home safely, and he did not show up for work on Thursday.

Rangers found his car Friday evening at a trailhead, and began searching first thing Saturday.
