2023 Map of Red Dome

About this map

Emigrant Trail Rd crosses the northern extent of this high desert landscape, marking a corridor defined by historic movement through Box Elder County. The topography is dominated by the volcanic profile of Red Dome and the sprawling Matlin Basin to the east. Water management in this arid environment is anchored by Pugsley Reservoir, which is served by a dedicated network including Pugsley Reservoir Rd and the W Loop Pugsley Reservoir Rd. To the south, the Old Railroad Grade Rd traces a linear path across the basin floor, likely following the decommissioned alignment of the First Transcontinental Railroad. This intersection of early pioneer trails and late 19th-century rail infrastructure illustrates the evolution of western transit across the Horse Hills.
