New Hampshire rte 111, to the America's Stonehenge signs.
America's Stonehenge is an awe inspiring place. The entire area was, at some point, a village made from stone. Lairs, sacrificial table, hallways, stair cases, everything made from pure NH Granite. I finally did a tour of this place, after living in NH for 40 years.
A somewhat "Historical" structure. A doorway made from granite at the end of a granite wall.
