A 54.2 °C sodium chloride-sulfate-bicarbonate spring carrying enough sulfide to qualify as a sulfur-bearing source, with the faint rotten-egg note of H₂S layered over the chloride salinity. Alkaline pH 8.4 gives the slippery beauty-water feel on the skin, balanced by sulfate body and bicarbonate softness. At 1,566 mg/kg of dissolved solids it sits in the moderately mineralized band — present on the body without ever feeling heavy.
