Chaco Culture National Historical Park, near Farmington, New Mexico, preserves one of America's richest and most fascinating cultural and historic areas. In Chaco Canyon, a desert valley in northwestern New Mexico, between the early AD 800s and the late 1200s, the Anasazi created a civilization whose architecture, social organization and community life reflected a high degree of sophistication. Large multi-story stone villages and an impressive 400-mile road system exemplify their engineering and construction talents.
