A sodium-calcium sulfate-chloride spring, hot at the source (50.6 °C). The sulfate fraction gives it a settled, mineral body, with a salty edge from the chloride sub-type. Neutral in pH and moderately mineralized at 1,090 mg/kg of dissolved solids. A generous 129 mg/kg of metasilicic acid leaves the kind of thin silica film that makes skin feel noticeably smoother afterwards.
