Utah Pillar

After a monolith structure had been spotted in Utah and subsequently been removed by an unknown party, another mysterious metal monolith has appeared in the US. Local media has reported that the monolith stands atop a mountain in California and that unlike its Utah sibling, the monolith in California wasn't strongly attached to the ground and looked like it could be easily knocked over.

The bureau said it had not removed the monolith, which it considers “private property.”
The Utah Department of Public Safety said on Monday that it had found the object while surveying for bighorn sheep.

A mysterious 3.6m tall metal pillar found recently in the Utah desert has been sought out by a number of tourists eager to have their photo taken with it. Discovered by a helicopter crew surveying bighorn sheep in the area, the monolith displays no indications of how it was placed there or for how long it has been in place.
Current speculation suggests it may be the work of the late John McCracken, a New Mexico based artist who passed away in 2011 and was known for his large freestanding sculptures of pyramids, cubes, and shiny slabs.
Local authorities are keeping the location of the pillar a secret, fearing hikers may risk their lives attempting to find it.

State wildlife officials have discovered a strange metal object from the air while flying a helicopter in the wilderness of southern Utah. The men and the pilot Bret Hutchings had been out counting bighorn sheep when a biologist spotted the shimmering column hidden in a rock niche far from any civilization.
Hutchings cannot say what the thing is, but it reminds him of the moon monolith from Stanley Kubrick's famous science fiction film "2001: Space Odyssey". "I suspect that a New Wave artist set this up," he said.
