1986 Map of Bobs Flat

About this map

The Humboldt River winds through the western edge of this Nevada landscape, where the historical Old Calif Trail traces an Approximate Route across the desert floor. This 1980s provisional survey illustrates the expansive terrain of Boulder Valley and the northern reaches of Whirlwind Valley, separated by the broad basin of Bobs Flat. The map documents the intersection of historical transit corridors and modern infrastructure, featuring a Wooden Pole Trans Line and a large Pipeline that cuts through the valley. Small markers of land use, such as a Corral and various Sand Areas near the river, punctuate the open space. Water management and drainage are represented by intermittent features like Bob Creek, Mack Creek, and the natural depression of Long Draw, reflecting the arid geography of the Eureka and Nevada county borderlands.
