2012 Map of Last Chance Range SW

About this map

Eureka Valley dominates this arid landscape in Inyo County, situated between the steep rising slopes of the Last Chance Range and the remarkable geologic formations of the Eureka Dunes. The topography is characterized by a complex network of ephemeral washes and alluvial fans that drain from the high peaks toward the valley floor. Human presence is sparse, represented primarily by S Eureka Rd winding through the northern portion of the terrain. The southeastern corner of the sheet transitions into the narrow confines of Dedeckera Canyon, revealing the stark relief typical of the High Sierra's eastern desert reaches. This 2012 survey documents the geomorphology of the region with precision, illustrating the relationship between wind-driven sand deposits and the bedrock geology of the surrounding mountains.
