Summary based on the NamUs case record (MP61622) and 2 other sources
Arthur Estes, a 25-year-old man, went missing on May 24, 1976, during a hiking trip in Yosemite National Park. He was dropped off at the junction of Tioga Road and May Lake Road to begin a two-day hike, with plans to trek toward Yosemite Valley via the Snow Creek Trail. His last known location was near May Lake, a popular area for hikers. Estes was an experienced hiker, standing 5'10" and weighing 165 lbs at the time of his disappearance.

Despite extensive searches, no trace of him was ever found. The area where Estes disappeared has been associated with other missing persons cases, adding to the mystery. Authorities and his family were left without answers, and his case remains unsolved decades later.
