Crystal (Madsens) Hot Springs near Honeyville flows at 129°F with extraordinarily high mineralization of 40,700 mg/L TDS, approaching seawater salinity with 14,600 mg/L sodium and 24,400 mg/L chloride.
The spring emerges at 4,268 feet elevation in Box Elder County's Cache Valley region, just 4 meters from a road in the agricultural lowlands between the Wellsville Mountains to the east and the Great Salt Lake to the west. This northern Utah setting receives 17.7 inches of precipitation with 43.1 inches of snow, supporting farmland and pasture in the valley floor. The extreme mineral content reflects deep circulation through ancient sedimentary formations, creating one of Utah's most saline thermal springs.
History of Crystal (Madsens) Hot Springs
The Crystal name references the spring's historical commercial use, while Madsens acknowledges family ownership and development. The site operated as a commercial soaking resort beginning in the early 20th century, capitalizing on the hot, highly mineralized water for therapeutic claims common in that era. The spring's accessibility and impressive heat made it a regional attraction. Current commercial status and facilities require verification.
The roadside location provides easy access, though current operating status as a commercial facility should be confirmed before visiting. The 129°F water requires cooling for safe bathing. Extreme salinity creates buoyancy similar to Utah's other salty hot springs. Box Elder Campground near Mantua Reservoir, 22.1 kilometers away, offers developed camping. Spring through fall provides optimal weather; winter access is generally feasible but cold air temperatures contrast sharply with the hot water.
