The Grand Canyon draws five million tourists a year. What most visitors don’t know is that the canyon is underexplored and far more mysterious than we imagine. Rumors talk of unexplained magnetic anomalies, ghostly figures seen by hikers, constant UFO sightings, and hidden caves sealed off by the government. The Grand Canyon is one of the world’s seven natural wonders, but it may also be one of its greatest secrets.
