Spring
An unnamed 145-degree spring flows near Boulder City at just 690 feet elevation, likely representing Gold Strike Hot Springs in the Lake Mead National Recreation Area. Recent USGS measurements confirm 54.2°C with high dissolved solids of 2,220 mg/L. The spring sits 329 meters from the nearest road, requiring a moderate hike into the canyon system.
The spring emerges in the dramatic desert canyon terrain near Hoover Dam at extremely low elevation. The location in the Colorado River gorge creates spectacular scenery with layered rock formations. Average annual temperature reaches 75.5 degrees with just 5.2 inches of precipitation and virtually no snow. The spring maintains temperatures 69.5 degrees above the already-hot ambient air. Water chemistry shows elevated sulfate at 679 mg/L and chloride at 645 mg/L.
The hike to Gold Strike Hot Springs involves steep canyon descent with technical sections requiring scrambling and rope use. Summer temperatures can be life-threatening, with canyon walls intensifying heat. Visit November through March only. Bring abundant water as the hike is strenuous. Multiple pools exist along the creek allowing temperature mixing. Check Lake Mead NRA regulations before visiting.
Wikipedia identifies this location as Gold Strike Hot Springs, a popular destination near Hoover Dam. The springs serve day hikers descending the canyon from parking areas above. The 1980 NOAA inventory documented the springs without a specific name designation. The Lake Mead National Recreation Area encompasses the site.
The water at Spring is neutral (pH 7.1) with 2220 mg/L total dissolved solids. It is notably rich in calcium (may support bone density and joint health), sodium (supports circulation and skin hydration), and sulfate (traditionally used for skin conditions and inflammation).
