The Utah Department of Public Safety said biologists spotted the monolith on Nov. 18, a report that garnered international attention.
While Utah officials did not say specifically where the monolith was located, people soon found it on satellite images dating back to 2016 and determined its GPS coordinates, prompting people to hike into the area.
Reporters with The Salt Lake Tribune hiked to the spot on Saturday and confirmed that it was gone.
“This was just a once-in-a-lifetime experience that we couldn't miss out,” Marino told KUTV.
On the way, they passed a long-bed truck with a large object in the back and he said he joked “oh look, there's the Utah monolith right there,” he said.
