Fred Comstock was 19 when he vanished on September 1, 1975, while hiking in Yosemite National Park. He had been at Vogelsang High Sierra Camp with a female companion and her son, and the plan was for Fred to hike back to Tuolumne Meadows, retrieve the companion’s car, and drive it to Yosemite Valley to meet them. He never arrived and his personal belongings, including his wallet, were left in the vehicle, suggesting he did not reach the car.

The distance and terrain between Vogelsang and Yosemite Valley make the solo assignment notable. Despite searches, no trace of Fred has been found and the circumstances of his disappearance remain unclear. The investigation remains open but has produced few leads over the years.

If anyone hiked that route in late August or early September 1975 or has information about Fred’s movements that day, please share what is known.
