A hot 64.2 degrees Celsius spring classified as a simple thermal source, neutral at the wellhead (pH 6.6). Sensory notes give it character: colorless and clear, with a faint tart edge on the tongue and a quiet earthy note. Total dissolved solids are light (370 mg/kg), but metasilicic acid runs to a generous 151.5 mg/kg, leaving the kind of silica film that makes skin feel noticeably smoother afterwards.
