Chaco Canyon: Chaco Canyon National Monument
built 606 days ago
In 1949, Chaco Canyon National Monument was expanded with lands deeded from the University of New Mexico. In return, the university maintained scientific research rights to the area. By 1959, the National Park Service had constructed a park visitor center, staff housing, and campgrounds. As a historic property of the National Park Service, the National Monument was listed on the National Register of Historic Places on October 15, 1966. In 1971, researchers Robert Lister and James Judge established the Chaco Center, a division for cultural research that functioned as a joint project between the University of New Mexico and the National Park Service. A number of multi-disciplinary research projects, archaeological surveys, and limited excavations began during this time.
