About this map

The San Juan River carves a deep path through this corner of San Juan County, Utah, serving as the physical and political boundary between the Glen Canyon National Recreation Area and the Navajo Indian Reservation. This desert landscape is defined by its massive flat-topped formations, including Pollys Mesa and Douglas Mesa, which rise sharply above the intricate drainage networks of Slickhorn Canyon and Johns Canyon.

Navigational challenges along the river are marked by the presence of Government Rapids, while topographic landmarks like Hat Rock and Point Lookout provide clear orientation points for those navigating the high plateau of Cedar Mesa. The map illustrates a transition from the protected federal recreation lands north of the river to the sovereign tribal lands to the south, highlighting how the river's course dictated historical and modern land management boundaries.
