Photos: Mysterious monolith found in Utah desert

A mysterious silver monolith discovered in the Utah desert has disappeared less than 10 days after it was spotted by wildlife biologists.

A mysterious monolith similar to the one found in Utah was recently spotted in Romania. Also similar to the one in Utah, it then suddenly disappeared.

In the mystery of the monoliths, another of the curious structures has been spotted, this time on the Isle of Wight, off England's south coast.
