Fairbanks Spring, Soda Spring
Fairbanks Spring emerges at 81°F within Ash Meadows National Wildlife Refuge, a federally protected wetland complex supporting critically endangered desert pupfish and other rare species. Water chemistry shows moderate mineralization with 408 mg/L total dissolved solids, calcium-magnesium-sulfate composition, and near-neutral pH of 6.9. The spring flows just 3.7 meters from IMV Alt Road under restricted public access managed by US Fish and Wildlife Service.
At 2,250 feet elevation in the Mojave Desert of southern Nye County, the spring occupies one of North America's most significant desert oasis ecosystems where over 30 springs and seeps feed wetland habitats across the valley floor. Ash Meadows sits in a broad basin flanked by barren mountain ranges, where thermal groundwater rises through carbonate aquifers to create isolated wetland ribbons in otherwise arid terrain receiving less than 4 inches of annual precipitation. The refuge encompasses 23,000 acres of alkali flats, mesquite bosques, and spring-fed pools sustaining plant and animal communities found nowhere else on Earth.
The Ash Meadows spring complex has supported human presence for at least 10,000 years, with Southern Paiute groups utilizing the reliable water and game. The area was claimed for ranching and farming in the early 1900s, with spring waters diverted for alfalfa cultivation and livestock. By the 1960s, proposed commercial development threatened the ecosystem until designation as a National Wildlife Refuge in 1984 secured permanent federal protection. The "Soda Spring" name references carbonate chemistry common to many Ash Meadows thermal features.
Access requires advance permission from refuge staff; unauthorized entry is prohibited. The refuge operates dawn-to-dusk hours with no overnight use permitted. Spring and fall offer moderate temperatures, while summer heat regularly exceeds 110°F. Winter is mild but occasional freezes occur. Roadside location makes viewing easy when access is granted. Combine visits with boardwalk tours of other refuge springs and endemic pupfish habitat. Bring sun protection and ample water.
