The largest known dolmen in North America, with a 90-ton capstone,
located at North Salem, NY. It was incorrectly attributed to
“the action of the Ice Age”, which probably should mean, the Boulder is not from that area and got there by Ice movements, however that does not mean the boulder wasn’t used to build a Dolmen.

Up to you what you believe, for me, it’s clear that this is not a natural accident we are looking at
