An 8-Year-Old Walked Into Yellowstone Forest In 1966 — Largest Search in Park History Found Nothing

On April 12, 1966, eight-year-old Dennis Eugene Johnson vanished from a picnic area in Yellowstone National Park — in broad daylight, surrounded by his family, in less time than it takes to finish a sentence. What followed was the largest search in Yellowstone's history: 100 square miles, tracking dogs, aircraft, military personnel, three full weeks — and not a single footprint, not a torn piece of clothing, not one physical trace of a sixty-pound boy who was there one moment and gone the next.
