Boulder, Colorado

Location Accuracy

Two monoliths have been “discovered” in Boulder, Colorado, however they look suspiciously similar. Many theorize that the same person put the monolith up in Chautauqua Park, snapped a photo, then moved it to a location outside a Taco Shop in downtown Boulder. Regardless, this monolith is so far unexplained. For now, it will be counted as one monolith.
