About this map

Tsaya and the surrounding high desert terrain of the Eastern Navajo Agency are defined by a complex network of arid drainage systems and service routes. This 2020 landscape is dominated by the Chaco River and its numerous tributaries, including Rock Wash, Alamo Wash, and the notably named De-na-zin Wash. The settlement of Delnazini sits near the heart of this region, where the terrain transitions toward the distinct Tsaya Canyon and the high plateaus of Split Lip Flats.

Infrastructure is primarily composed of Bureau of Indian Affairs routes and county roads, such as Indian Svc Rte 7000 and Co Rd 7197, which connect isolated water features like Tanner Lake and Dog Eye Pond. The map provides a detailed view of the modern land management and hydrological patterns in San Juan County, reflecting the continued importance of seasonal watercourses like Coal Cr in this portion of the Navajo Nation.
