Park sign:
“Located near the summit of Mystery Hill is a massive complex of stone chambers, walls and large standing stones, both radio-carbon dating (C-14) and the placement of the astrologically oriented standing stones indicate this site was constructed at least 4,000 years ago. Like the Stonehenge of England, America’s Stonehenge accurately plots many solar and lunar events, such as soltices and equinoxes, as well as many ancient holidays.”
