Mysterious Stone Sites [Paperback]

There are mysteries in the woods of the Hudson Valley of New York and northern New Jersey. There are stone sites that are assumed to be the work of colonial farmers, but author and researcher Linda Zimmermann has found compelling evidence that disputes this misconception. Zimmermann explores stone chambers, perched boulders, standing stones, and massive walls that may just be unique historical treasures that must be studied and preserved. Could they be the work of Native Americans or Pre-Columbian voyagers?
