The Salt-Gorge came into being thanks to human help: in early times, the exploitation of salt resulted in residual sumps that filled up with rain, then started to dissolve, gradually turning into lake-chains. The gorge appeared in the valley situated between these lakes, the Corund-creek also sheering its course in the same direction.

Mud-baths have been renewed by collective work on the spot.

Among the crystalline rocks of these salt-mountains of Praid grows the common glasswort (Salicornia herbacea).
