2017 Map of The Hogback South

About this map

The Hogback rises as the dominant geological formation in this high-desert landscape of northwestern New Mexico. This survey by the U.S. Geological Survey documents the drainage patterns and transportation network of the San Juan Basin during the late 2010s. The Chaco River meanders northward through the center of the quadrangle, joined by seasonal tributaries like Cottonwood Arroyo and Coal Cr. The map details a complex system of local infrastructure, including Bureau of Indian Affairs routes such as Indian Svc Rte 3017 and Indian Svc Rte 5082. These service roads, along with the Pinto Reroute, underscore the area's importance for local transit and utility access within the Navajo Nation, providing a technical view of the land's contemporary use and its ancient topographical features.
