For the third time in a week, a mysterious metal monolith has captured the public's attention. This time, a 10-foot-tall steel obelisk was found atop Pine Mountain in Atascadero, California, reports the Guardian, which features pictures hikers have posted to social media. Unlike the monolith found in Utah, this one does not appear to be planted in the ground, and "could be knocked over with a firm push," the Atascadero News reports. The Utah one, and the first "copycat" found in Romania, have both disappeared. (More strange stuff stories.)
