2018 Map of Tule Dam Spring

About this map

The historical Pony Express Trl cuts across the arid expanse of Diamond Valley, following a path that remains etched into the Eureka County landscape. This high-desert terrain is defined by critical water sources like Tule Dam Spring, Sulphur Spring, and the seasonally wet Tule Marsh. The map illustrates the transit corridor between the mountains and the valley floor, where Saddler Brown Rd winds through the topography. Notable geological landmarks provide natural passage through the ridgelines, including Mulligan Gap to the west and Tyrone Gap further south. The drainage of Garden Pass Cr serves as a subtle hydrological feature in an otherwise dry environment, highlighting the essential relationship between water access and historical travel routes in the Great Basin.
