The Hogback ridge dominates this Northwest New Mexico landscape, serving as a dramatic geological divide just south of the San Juan River. The 2017 survey reveals the intricate water management systems essential to the region, including the Hogback Canal and the Fruitland Irrigation Canal, which parallel the river's course to support agricultural activity near the settlement of Waterflow. The ephemeral Chaco River and Chinde Wash carve paths through the arid terrain, highlighting the complex drainage patterns of the Shiprock Agency area. Researchers can trace the modern road network, from San Juan Charter Rd to Hwy 36, as it navigates the varying elevations of this high-desert environment where natural springs like Hogback Spring remain notable landmarks.
