2020 Map of Tunnel Spring

About this map

Tunnel Spring is a critical water source in this arid corner of Millard County, situated on the eastern slopes of the Tunnel Spring Mountains. This high-desert landscape is defined by its dramatic elevation changes between the central peaks and the surrounding basins of Antelope Valley and Pine Valley. To the west, East Antelope Reservoir collects seasonal runoff, while the southern terrain is marked by the distinct topography of the Halfway Hills and the geological formation of Warm Cove Ridge. A grid of rural roads, including the evocatively named Cowboy Rd and various numbered routes like S 28400 West St, provides access across the basin floors. The distribution of these roads and water features reflects the ongoing management of this open range by agencies like the Bureau of Land Management.
