I seriously hope this piece of artwork, as it is clearly intended to be, is preserved. Utah already has a tradition in land art with Robert Smithson's, Spiral Jetty [1].
Look it’s not aliens but there is nothing clearly making this art. It’s far more likely a memorial for someone or something. It’s hidden. It’s expensive. And quite frankly, would be a shitty rip off if it was art.
