1988 Map of Chamisa Tank

About this map

The Havasupai Indian Reservation dominates this high-altitude landscape south of the Grand Canyon National Park rim. This 1980s provisional survey illustrates a remote region where water management is the primary marker of human activity, defined by a network of cattle tanks and catchment basins. Named features such as Watahomigie Tank, Cecil Dodd Tank, and Akaba Tank suggest the historic ranching and tribal land use of the Coconino plateau. The terrain is deeply grooved by seasonal drainages including Heather Wash, Prairie Wash, and Coconino Wash, which navigate the transitions between the reservation, the Kaibab National Forest, and the Grand Canyon National Game Preserve. The map serves as a detailed record of the boundaries and essential water sources of this arid corner of Arizona before late-twentieth-century shifts in land management.
