On June 18, 1823, while leading an expedition to the heart of Hopi lands, Mexican soldier José Antonio Vizcarra (soon to be the third Mexican governor of New Mexico) dipped into a canyon and came across the remains of the largest series of structures built by man in North America. What Vizcarra found in that canyon was more than impressive — it was a rare design that, to this day, stands the test of time. Constructed of sandstone and timber, Chaco Canyon was the cultural center for the Ancient Pueblo people between 900 – 1150 AD. Now managed by the National Park Service, Chaco Canyon is a testament to human ingenuity and the merging of spiritual life, community and commerce.
