A newly discovered road, believed to have been part of an Indigenous ritual landscape, has shed light on the advanced cosmology and ceremonial practices of the Chacoan civilization. This ancient road, hidden beneath the sands of time, was recently uncovered using public maps based on lidar technology, revealing a path that extends nearly 4 miles (6 km) between natural springs. The road, cut into sandstone bedrock with a width of approximately 30 feet (9 meters), is much larger than necessary for a society without wheeled vehicles or pack animals. It is part of a larger network of roads constructed by the Chacoans, who thrived in the American Southwest between A.D. 850 and 1250.
The Chacoan road network is remarkably extensive, covering an area roughly the size of Ohio. The roads align with significant celestial events such as the winter solstice sunrise over Mount Taylor, indicating their use for sacred processions and ritual activities. The alignment suggests a deep connection between the Chacoans' cosmology and the physical landscape they inhabited.
"One of the really exciting things about the work we've been doing with Chacoan roads is that they're forcing us to reconceptualize what a road might be, what a road might mean,"

The Chacoan road in question is surrounded by intriguing features, including a "herradura," or a horseshoe-shaped wall of rocks, which may have served as a roadside shrine. These structures likely acted as focal points for ritual activity along the route. The presence of such features indicates that these roads were designed not just for physical transit but also as spiritual conduits that facilitated ceremonial journeys.
The discovery and analysis of this road have prompted scholars to revisit their understanding of ancient infrastructure. Unlike modern roads intended primarily for transportation, these pathways served a dualistic purpose deeply embedded in the Chacoan cosmology. The road's significance extends beyond its physical presence, embodying spiritual and cosmological principles central to Chacoan life.
"The geography of Chaco's domain is uniquely preserved by its roads, as well as much of Chaco cosmology,"

However, these historical treasures face threats from modern energy projects on public lands. These developments pose a risk to the preservation of this vital chapter in Pueblo and Navajo history. Protecting these roads and their surrounding landscapes is crucial to maintaining the integrity of Indigenous cultural heritage.
The Chacoan civilization's achievements in constructing such an intricate network of roads without modern technology continue to amaze archaeologists and historians alike. The sophistication of their engineering reflects their advanced understanding of both terrestrial and celestial domains. By aligning their roads with astronomical events, the Chacoans demonstrated an impressive integration of science and spirituality.
