2020 Map of The Hogback South

About this map

The Hogback dominates this corner of the San Juan Basin, its distinctive ridgeline cutting across the northwestern quadrant. Below this geological landmark, the Chaco River meanders southward through a desert landscape defined by broad drainages and service roads. The water network is further detailed by the inclusion of Coal Cr and the winding course of Cottonwood Arroyo, which join the primary river system. This 2020 topographic record shows a territory managed through specialized infrastructure, notably the Indian Svc Rte 5017 and Ind Sr 5083. The modern character of the area is underscored by the presence of the Pinto Reroute and the numbered route N 4104, mapping the movement of people and industry through the Shiprock Agency region.
