2014 Map of Saguaro Gap Well

About this map

Growler Wash meanders across the arid expanse of Growler Valley in this Pima County landscape, which is defined by the stark transition from flat desert floor to the steep rises of the Granite Mountains. The hydrology of the area is critically important, as evidenced by the isolated Saguaro Gap Well, a singular point of water infrastructure in a region dominated by ephemeral drainage patterns. This 2014 survey documents the topographic character of the Saguaro Gap, where the terrain creates a natural passage through the mountain range. The map provides a detailed view of the Public Land Survey System divisions, showing the grid of townships and ranges that impose a human order on this sparsely settled desert environment.
