Or maybe it's the same monolith that inexplicably appeared, then disappeared, in Utah last week. The construction of this monolith on Pine Mountain in Atascadero, California is definitely cruder, suggesting that's an imitation of the original alien object. Atascadero News describes it:
The three-sided obelisk appeared to be made of stainless steel, 10-feet tall and 18 inches wide. The object was welded together at each corner, with rivets attaching the side panels to a likely steel frame inside. The top of the monument did not show any weld marks, and it appears to be hollow at the top, and possibly bottom.
Unlike its Utah sibling, the Atascadero obelisk was not attached to the ground, and could be knocked over with a firm push. The Atascadero News estimates it weighs about 200 pounds.
The material appeared to be stainless steel, similar to a hood above the stove in a commercial kitchen.
So it's more likely to be from pranksters rather than our actual alien visitors.
