About this map

The San Juan River carves through the heart of this landscape, its waters widening into the eastern reaches of Lake Powell near the southwestern corner of the quadrangle. This 1989 provisional edition illustrates a convergence of administrative and natural boundaries, where the Glen Canyon National Recreation Area meets the northern edge of the Navajo Indian Reservation. The terrain is defined by dramatic elevation changes and named landmarks such as Shaw Arch and Government Bird Rock.

Remote mesas like Douglas Mesa and Polly Pasture overlook deep incisions like Grand Gulch and Slickhorn Canyon. For the researcher, the map documents early infrastructure and land use, from a system of Foot Trails and Pack Trails to specific industrial markers like the Drill Holes located north of Slickhorn Rapids. The placement of a seasonal Spring near the reservation boundary highlights the critical role of water sources in this high-desert environment.
