I guess this lock was put on some time ago and has not been opened for a while. Volcanic mineral laden steam at work.

Where the smelly steam escapes from the ground, condensation and evaporation leaves behind fantastic crystal formations of sulphur. Primarily yellow, but at times tending towards green, depending on the minerals in the rocks where they form, I guess.

That's Jo down there. In the crater. This is not an extinct volcano, but not too active. Dormant. Stinking sulphurous gasses hiss out of various vents around, mainly near the rim. Is it guaranteed not to erupt? Nothing is guaranteed when it comes to things like volcanoes. Just unlikely... Island of Nisyros, not far from Kos, Greece.
