Stinking Hot Springs
Stinking Hot Springs produces 118-degree water with extreme mineral concentration, containing 33,800 milligrams per liter of total dissolved solids dominated by 19,000 milligrams per liter of chloride. This highly saline thermal system flows 67 degrees above ambient air temperature in Box Elder County, requiring a 232-meter walk from the nearest road.
The springs emerge at 4,261 feet elevation on the flats southwest of Bear River City, positioned along the eastern edge of the Great Salt Lake basin where ancient lake sediments define the topography. The surrounding landscape receives 16.6 inches of annual precipitation and 30.6 inches of snow, supporting sparse vegetation adapted to alkaline soils. Salt-tolerant grasses and shrubs dominate the immediate area while the Wasatch Range forms the distant eastern horizon across the Bear River valley.
The evocative name derives from hydrogen sulfide and other volatile compounds produced by subsurface bacterial activity in the highly mineralized geothermal system. Locally known as Stinky Springs, the site represents one of four hot springs aligned along the Wasatch Range's western front in Box Elder County. Documentation of historical use remains sparse, though the distinctive odor has made the location a recognizable landmark for area residents across generations.
Visit during cooler months when high heat and humidity become less oppressive; summer conditions can prove uncomfortable. The quarter-kilometer walk crosses open terrain with minimal shade, requiring sun protection and adequate water. The extreme salinity and temperature make this primarily a geologic curiosity rather than a bathing destination. Box Elder Campground provides developed facilities 25.7 kilometers away near Mantua Reservoir.
