A seep in the old Plazaola railway tunnel forms red concretions over plant forms, at a point with a watershed divide.
Descrizione
Concrezioni
In the old Plazaola railway tunnel, roughly at its midpoint, there is a significant seep that forms reddish-toned concretions because iron pyrites abound in the terrain.
Idrologia
The seep takes advantage of various plant forms that are coated, and at this point the phenomenon of the watershed divide exists.
