Túnel del Sumidor
Túnel del Sumidor, a cavity formed in gypsum of the Keuper within the axis made up of els Brolladors, the tunnel itself and the fountain of la Saraella. It is the most important cavity in the world in terms of level changes and has water that turns from fresh to salt.
The tunnel runs through gypsum materials of the Keuper and forms an axis with els Brolladors and the fountain of la Saraella, so the cavity is understood as part of a larger hydrological system. It is the most important cavity in the world in terms of level changes, a feature that defines its interest. Its waters turn from fresh to salt along the route, which adds a singular element to the behaviour of the water inside. The site therefore brings together geology, hydrology and an underground route that sets it apart, and for that reason the tunnel is studied as a particular case among cavities in gypsum.
