While the ancient inhabitants of America's Stonehenge may not have had indoor plumbing, they did have a complex series of storm drains which worked to keep the site dry from rain and snow-melt. Visit America's Stonehenge to see these drains and the artifacts which have been excavated from them! We hope to continue our work with GPR to map these intriguing structures. #americasstonehenge #ancient #history #archaeology #stonework #megalith #museum #tour #salem #newhampshire
