2023 Map of The Hogback South

About this map

The Hogback dominates the northern terrain of this San Juan County landscape, providing a sharp geological boundary that defines the local topography. This 2023 survey by the U.S. Geological Survey illustrates a dry-wash environment where the seasonal waters of the Chaco River and Coal Creek carve through the high desert. Further south, Cottonwood Arroyo cuts across the plains, indicating the drainage patterns essential for understanding this arid region's geography. The map records a network of service and local roads, including Indian Svc Rte 5017 and Pinto Reroute, which connect remote sections of the Navajo Nation. These routes, alongside Ind Sr 5083, highlight the modern infrastructure supporting land management and transportation in this sparsely populated corner of New Mexico.
