Bruce Parker Pike, 47, vanished on August 2, 2006, while camping at Indian Creek Campground in Yellowstone National Park, Wyoming. His vehicle was later found abandoned inside the park, and there have been no confirmed sightings of Pike since his last known appearance. He was 5 feet 11 inches, about 185 pounds, and wore eyeglasses at the time he went missing.

Authorities have treated the case as a lost/injured disappearance; Texas investigators have been involved because of Pike’s ties to that state. Extensive searches in Yellowstone’s vast, rugged terrain have not produced additional clues, and the case remains open with officials seeking public help.

If anyone has information about Pike’s movements in early August 2006 or recalls seeing his vehicle in Yellowstone, please come forward.
