The discovery of a 5000-year-old Sun Temple and its exquisite "time machine" -- a Stone Age calendar -- led scientist Gordon Freeman to ground-breaking discoveries in Stonehenge. During field work and research from 1989 to 2006, Freeman found striking similarities between the surface geometry of the two sites. These similarities push back the boundaries of written history and have far-reaching implications for North American and European history. Gordon Freeman's new book, Canada's Stonehenge outlines these discoveries using dramatic photographs and maps which throw new light on the genious of the First Peoples of North America.
