A mysterious metal object has shown up along a northern San Luis Obispo County hiking trail.
The monolith on Atascadero’s Pine Mountain has three sides and is 12-feet tall, according to City officials.
While when the object was placed there or by who hasn't been revealed, locals say it was a recent addition.
Pine Mountain is part of the Atascadero Land Preservation Society (ALPS), which says it doesn't have information on the monolith.
Monolith structures are on the minds of many after the discovery of one in Utah last month. It was later removed by an unknown party.
