2017 Map of Tanner Lake

About this map

Tsaya sits at the southern edge of this landscape, positioned near the mouth of Tsaya Canyon and a complex network of seasonal drainage routes. The topography is defined by the intermittent flow of De-na-zin Wash and Rock Wash, which carve through the high desert terrain. Further north, the settlement of De-na-zin and the namesake Tanner Lake provide local reference points for a region largely defined by its open spaces and natural landmarks like Split Lip Flats and Dog Eye Pond. The distribution of roads, including Indian Svc Rte 7000 and Co RD 7710, reveals a low-density settlement pattern typical of the Eastern Navajo Agency. This 2017 survey documents the modern infrastructure of San Juan County, highlighting how travel and water management revolve around the major washes and mesa edges.
