The sharp monocline of The Hogback dominates this landscape in San Juan County, cutting through a high desert region defined by the confluence of the San Juan River and the Chaco River. In the early 21st century, this area represents a complex intersection of natural geology and human engineering. The presence of Hogback Field indicates the importance of local energy extraction, while the Fruitland Irrigation Canal and Hogback Canal demonstrate how water is diverted from the major rivers to support the surrounding environment. To the northeast, the Jewett Waterflow Valley serves as a significant riparian feature. Transportation across these arid lands is managed through a network of specialized routes, including Indian Service Route 162 and San Juan Charter Rd, which provide access to remote areas like Hogback Spring and the drainage of Chinde Wash.
