Studying the origins of the aptly named Mystery Hill megaliths, also known as America’s Stonehenge, whets one’s curiosity but does not satisfy—unless one is satisfied by the excitement of confounding mystery alone.
The site, in North Salem, New Hampshire, includes stone monoliths and chambers spread across 30 acres. The stones are said to have complex astronomical alignments. A 4.5-ton stone slab that seems to be the focal point of the site may have served as an altar for sacrifice. It is grooved with a channel for draining, possibly the blood of a victim.
