Mysterious desert monolith disappears, heralding either doom or reveal of viral ad campaign

Last week, a mysterious metal monolith was discovered in a remote area of Utah. A few investigators, failing to heed the lessons of basically every sci-fi and horror story ever told, arrived, proceeded to touch the thing, and announced basically that none of them knew how the hell it had come to be implanted in the desert floor. Now, the monolith has disappeared just as inexplicably as it arrived.
Utah’s Bureau Of Land Management tweeted on Saturday that “the illegally installed structure, referred to as the ‘monolith’ has been removed by an unknown party.” The account recently followed up on that message to say only that, “we may not know if an extraterrestrial or earthling installed the ‘monolith’ structure, but we can confirm that it has been taken by an unknown party or parties.”
