sulfur, but not warm

This cold sulphurous spring in Greece is a naturally occurring mineral source that carries dissolved sulphur compounds — giving it the characteristic aroma of hydrogen sulphide — without the geothermal warmth typically associated with sulphurous springs. Cold sulphurous springs are geologically distinct from their hot counterparts but share a similarly rich mineral character, and their waters have traditionally been associated with drinking and bathing customs within a long thermal heritage. The spring offers an unusual and scientifically interesting encounter with sulphurous mineralisation in the absence of geothermal heat.
