Sweetwater Station Warm Springs
Sweetwater Station Warm Springs emerges at 90°F near Arapahoe in Fremont County at 6,640 feet elevation, requiring a short 103-meter walk from roads. Recent USGS sampling documented 29°C water with pH 7.5 and elevated dissolved minerals including 130 mg/L sodium, 220 mg/L sulfate, and 120 mg/L chloride, creating a moderately mineralized warm spring.
The spring sits in the semiarid basin country of central Wyoming where annual precipitation totals just 12 inches and snowfall averages 52 inches. The landscape consists of sagebrush steppe with scattered juniper on rolling terrain crossed by the historic Sweetwater River drainage system. At this elevation, the setting lacks the dramatic mountain backdrop common to Wyoming's higher springs, instead offering open views across basin and range topography.
The name derives from Sweetwater Station, one of many stage stops and military outposts established along the Oregon, California, and Mormon emigrant trails in the 1850s-1860s. The spring likely served travelers and livestock along these routes. Current status shows no formal protection designation or development, suggesting it remains in relatively natural condition on private or undesignated public land.
The semiarid climate makes spring and fall the most comfortable seasons; summers are hot and winters cold. The short walk from the road makes access straightforward in dry conditions, though spring snowmelt or heavy rains may create muddy approaches. No facilities exist nearby. The warm rather than hot temperature and moderate chemistry suggest bathing potential, though water quality testing would be prudent.
