1982 Map of Horse Mesa

About this map

Navajo Indian Reservation lands dominate this borderland landscape, where the high desert terrain of the Red Rock Valley meets the interstate line between Arizona and New Mexico. The map documents a rugged environment defined by seasonal drainages like Blackrock Wash and Red Rock Creek, which carve through the prominent Horse Mesa. Human presence is marked primarily by ranching and resource exploration, evidenced by scattered Corral locations and several Open Pit sites. Essential water sources such as Tse Clani Spring and Oak Spring are critical anchors in this arid region. The presence of multiple Drill Holes and Prospects suggests a mid-to-late 20th-century interest in the mineral potential of these ancestral lands, while the State Boundary Monument 24M provides a precise historical marker of the jurisdictional divide between Apache County and San Juan County.
