1987 Map of Jacobs Monument

About this map

Monument Valley terrain dominates this 1980s landscape at the border of Utah and Arizona. Situated within the Navajo Indian Reservation, the area is defined by massive sandstone formations including Jacobs Monument, Pickrell Mesa, and the broad elevations of Nokai Mesa and Hoskinnini Mesa. The topography reveals a complex network of drainage systems, most notably Copper Canyon and the headwaters of the East Fork and West Fork. This survey captures the region's physical character before the digital era, documenting traditional landmarks like Tse-dahascani and the precise jurisdictional line between San Juan County and Navajo County. The arrangement of these mesas and canyons illustrates the severe erosional patterns characteristic of the high desert plateau.
