About this map

Little Sahara National Recreation Area and its expansive Sand Dunes dominate the central landscape of this 1970s survey, illustrating a region defined by arid basins and resource-heavy mountain ranges. The eastern portion of the sheet reveals a dense network of industrial history within the East Tintic Mountains, where numerous operations like the Mammoth Mine, Iron King Mine, and Trixie Mine are clustered around the settlements of Eureka and Mammoth. This concentration of mining activity contrasts sharply with the western desert reaches near Keg Mountain and the Old River Bed.

Transportation corridors follow the natural topography, with the Union Pacific and Denver and Rio Grande Western railroads skirting the mountain bases to serve the remote outposts of Lynndyl and Jericho. The map also captures the boundaries of the Wasatch National Forest and Fishlake National Forest, highlighting the transition from the high Sheeprock Mountains down to the sprawling Dugway Valley.
