A Modern Look at Chacoan Communications

A thousand years ago, the Chacoan people communicated throughout their world using nighttime fires, and possibly reflective mirrors in the daytime. Signaling areas have been located on mesa tops, mountains, and Chacoan buildings throughout the Four Corners region. On May 29, 2007, park staff will participate in a region-wide demonstration, and attempt to communicate by mirrors with others located at Pierre’s Site, Huerfano Mesa, Mesa Verde, and Chimney Rock Pueblo and other Chacoan sites.

The climate of Chaco Canyon 1,000 years ago was very similar to the climate in the park today, with annual precipitation of only eight to nine inches. The Puebloans constructed water control features like dams, canals, and headgates for farming in such a dry environment.
