About this map

Topaz Mtn and the surrounding Thomas Range define this high-desert landscape in Juab County. This area is a significant site for mineralogy, highlighted by the location of Topaz Mountain, where the gemstone-bearing rhyolite has long attracted collectors and geological interest. The map tracks the network of desert routes that provide access to these remote reaches, including Weis Hwy and Brush Hwy, which intersect the expansive Dugway Valley.

Drainage and seasonal water sources are critical features of this arid terrain, marked by Little Valley Wash and the Dead Horse Tank to the northeast. To the west, the topography becomes increasingly complex as it rises toward Starvation Canyon and the ridges of the Thomas Range. These landforms, along with Antelope Ridge and the Pismire Knolls, illustrate the Basin and Range geological province's characteristic alternating valleys and mountain blocks.
