A series of linear roads were built around 1000 years ago all over the four corners area, but focusing on the Chaco Canyon region. We talk with Rob Weiner – archaeologist, anthropologist, and student of religion – whose research at the University of Colorado in Boulder focuses on monumental roads that the ancestors of the Pueblo and Diné people built about 1000 years ago here on the Colorado Plateau. We talk about the significance of these architectural monuments, how they are mapped out, and why it is important to preserve them.
