we realize that we know next to nothing about the Anasazi. We don’t understand their culture, we don’t understand their religion. We cannot read their petroglyphs and pictographs. We do not know what languages they might have spoken. We do not know why they covered the Southwest with lighthouses, shrines, roads, and signaling stations. We do not know why, in 1150, they suddenly abandoned Chaco Canyon, burned the roads, and retreated to the most remote, inaccessible canyons in the Southwest, building mighty fortresses in the cliff faces.
