2020 Map of Deer Mesa

About this map

Deer Mesa and Sisnathyel Mesa define this high-altitude landscape in the Eastern Navajo Agency, where complex drainage systems cut through the sedimentary layers of Sandoval County. The map details a network of ephemeral watercourses, most notably Tancosa Wash and Peña Wash in the north, and Torreon Wash as it winds toward the southeast. These arroyos and washes are critical markers of the local topography, influencing the placement of early transportation routes like Indian Svc Rte 23 and Pilon.
