About this map

The Chaco River and its intricate network of ephemeral drainages dominate this arid landscape in San Juan County. This modern survey illustrates the natural hydrology of the region, where seasonal waters move through major channels like Brimhall Wash and Hunter Wash. The terrain is marked by traditional navigation routes, including Indian Svc Rte 5 and Indian Svc Rte 5008, which cross the high desert plateaus. These roads provide critical access through the various sections defined by the Public Land Survey System, such as t24n r16w and t25n r17w. Smaller watercourses, notably At-eec-ni-di-tso Wash and Arroyo Medio, weave between the larger washes, showing the delicate erosion patterns and geographic character of this high-altitude basin. The map serves as a contemporary record of how local infrastructure interacts with the desert's natural water-carved geography.
