A sodium-and-iron chloride spring with bicarbonate softness layered in. It is genuinely iron-rich (about 80 mg/kg of Fe(II)), so the water turns faintly yellow and slightly turbid with a metallic taste once it meets the air. As a cold-mineral source in the low-20 °C range, it is reheated for bathing.
