>>1658021They truly are. Unfortunately, that particular site was demolished May 2018 (captured on Google Earth no less). I just revisited it today to pay respects, here is an identical shot to the other one.
Normally I wouldn't reveal its location, but since it's gone there's no secret. It was called "Space" by those who visited it, since climbing it at night would make you feel like you were going into space, and it was at the top of Wolf Mountain off Hwy 49 near Grass Valley, CA.
