Utah police said they would not launch a major investigation into the disappearance of a mysterious silver monolith that had attracted international attention after it was discovered in the Utah desert.
The San Juan County sheriff said the office did not have enough resources to devote a lot of time and energy to investigating who had taken the object, which was initially illegal because it was placed amid red rocks in remote areas without permission.
The creator of the monolith also remains a mystery. Authorities will accept tips from anyone who has seen anything suspicious about the discovery.
The monolith was spotted on November 18 by a crew of state helicopters who helped wildlife biologists count the big-horned sheep. It was about 11 feet high and appeared to be made of stainless steel.
Utah officials did not say exactly where the monolith was located, but people soon found satellite images of 2016 and determined its GPS coordinates.
Hundreds traveled to see the glittering, almost otherworldly object. The visitors parked the vehicles at factories and left behind, the Federal Office of Agriculture (BLM) said, adding that there was no parking, bathroom or mobile phone coverage on site and some cars had to be towed from a remote area after a stall.
The site is now empty except for a piece of rectangular metal covering a hole where the monolith stood.
The BLM reminded potential visitors that it was still illegal to drive on designated roads in the area.
