Blue Lake Spring
Blue Lake Spring maintains the 84°F geothermal pond known as Blue Lake, covering approximately 9 acres with depths reaching 60 feet at 4,260 feet elevation about 16 miles south of Wendover, Utah. The feature sits on the Utah Test and Training Range managed by the Air Force, though the lake and immediate surroundings are publicly accessible wetlands managed by BLM. Recent USGS data shows water at 29°C with elevated salinity.
The lake emerges improbably in the western Utah desert, creating an isolated wetland oasis surrounded by salt flats and barren terrain stretching to distant mountain ranges on all horizons. The area receives minimal precipitation (7.3 inches annually) with light snowfall (12.5 inches), making the permanent water body fed by thermal springs all the more remarkable. The Great Salt Lake Desert extends north and east, while the Nevada border lies just miles west. Sparse desert shrubs and salt-tolerant vegetation grow near the lake margins.
Blue Lake's name describes the water's distinctive color, likely caused by thermal spring chemistry, mineral content, or perhaps algal growth in the warm, permanent water. The feature sits on military lands (Utah Test and Training Range) established during World War II for bombing and gunnery training. Despite military control of surrounding areas, the lake itself and immediate wetlands received BLM management for conservation purposes. The thermal springs maintaining the lake represent deep geothermal circulation.
Access is restricted due to military range status; verify current public access with BLM or Hill Air Force Base before attempting visits. When accessible, the location lies far from services—bring all water, food, and fuel from Wendover. Roads may require high-clearance vehicles. The warm water supports unique biology in an otherwise harsh desert environment. No developed camping exists nearby. Visit spring or fall to avoid temperature extremes. The remote location demands self-sufficiency and careful trip planning.

- Warm-water soaking
The water at Blue Lake Spring is slightly alkaline (pH 7.5). It is notably rich in calcium (may support bone density and joint health), magnesium (known for muscle relaxation and stress relief), and sodium (supports circulation and skin hydration).
