Timothy John Barnes, 24, went missing during a solo hike in Yosemite National Park on July 5, 1988. He planned to hike from Tenaya Lake near Highway 120 to Polly Dome Lakes, about three miles, and was expected back by 4:30 p.m. Friends reported him missing the next morning after he failed to return.

Barnes was last seen wearing a white t-shirt with a red no symbol, gray sweatpants, worn white sneakers, and carrying a yellow day pack. He had an orthopedic pin in his left ankle and smoked Marlboro cigarettes. Park rangers and rescue teams conducted an extensive search but found no trace of him.

Barnes was declared legally dead on July 19, 1990, though no remains have ever been recovered. If anyone hiked that route or was in the Tenaya Lake or Polly Dome Lakes area on July 5, 1988, did you see Timothy Barnes or his gear?
