The Puig d'Adri volcano
The Puig d'Adri volcano is at the foot of the Rocacorba mountains, between Canet d'Adri, Montcal and Adri.
The materials it ejected while active are diverse, although it is worth highlighting the layer of lava some 12km (7.5 miles) in length, which goes from Canet until reaching Domeny. Perhaps the most well-known and visited part of this volcano in the area around the Torre spring, at the confluence of the Rocacorba and Rissec streams.
Here, the volcanic substrate has been eroded over a long period of time by the water, forming a series of deep and narrow gorges with a curious alveolar patterning.
