2014 Map of Black Tank

About this map

Black Tank and Nelson Tank serve as critical water collection points in this arid section of Coconino County, where the high desert landscape is defined by drainage patterns and seasonal catchments. This survey of the Black Tank quadrangle reveals a territory primarily organized by the Public Land Survey System, spanning townships t27n r4w through t26n r3w. The topography is marked by significant elevation changes, most notably at Long Point and along the course of Farm Dam Draw. Such maps are essential for understanding how water resources were managed across vast grazing lands and identifying remote landmarks like Little Sullivan Tank that provided vital stops in a water-scarce environment.
