The Utah monolith, a triangular structure comprised of sheet metal, has been in that location since 2016 but was just noticed recently in 2020. The discovery of the Utah monolith resulted in more monoliths created and placed in various locations. Thereafter, many of the monoliths have been removed due to improper placement. These monoliths, placed by various entities like artists and companies, have been sighted all over the world including several places in the United States. Artistic expression? I have my thoughts, but I am awaiting some explanation about the intended purposes; however, this might be impossible because in some instances, no one knows how the monoliths appeared. Source:
