The mysterious silver monolith has vanished, seemingly as quickly as it appeared over a week ago in a remote desert in southeastern Utah. After the monolith was discovered, adventurers flocked to the desert to see the otherworldly, 12-foot-tall metal column. Riccardo Marino was one of the first people to realize it was gone. “We noticed tire tracks from some kind of dolly or wheelbarrow that was hauling it out,” Marino said. All that was left at the site is the monolith’s base plate.
