About Stacey Ann Arras's case

Stacey Ann Arras was only 14 years old when she disappeared on July 17, 1981, in Yosemite National Park.

Stacey was with her father on a mule pack trip with 10 other members. On the day of her disappearance, Stacey, her father, and the 10 members stopped at Sunrise High Sierra Camp to rest for the night. According to records kept by the National Parks Service, Stacey left the camp to walk a short trail leading to a ridge, before heading out to take some pictures – but never returned.

One of the mule-pack members, a 77 year old man, was the last person to see Stacey. He said that he accompanied her on part of the hike, but stopped to rest while she continued forward. After a few moments had passed, he also stated that he asked a group of people, who were heading back from the trail that Stacey was on, if they had seen her, but they never saw the girl.

Once Stacey’s disappearance was reported, the search began. At the height of the search, there was at least 100 people involved; including teams of professional searchers, skin divers, dog teams, and other mountain climbers. Even the park’s contact helicopter spent more than 40 hours in the air – there was no sign of her.

The search was called off after 11 days from when Stacey disappeared.

To this day, Stacey remains missing. The National Park Service would greatly appreciate any information from those who may come across Stacey while hiking the area.
