Mystery Hill-America's Stonehenge
Additional Details:
| Two ancient radio-carbon dates have been the walls. Both were obtained from charcoal. The first, that of 1000 B. C. was done in 1969. The second date of almost 2000 B. C. was made in 1971. These dates indicate that Mystery Hill was built sometime prior to 2000 B.C. by an, as yet, unknown culture. |
