The south-eastern part of its territory includes the second highest point of Gran Canaria island, Pico de las Nieves ("Snows Peak") - 1,949 m (6,394 ft).

It exists because the explosive eruption by which the caldera collapsed was so powerful that the magma was pulverized in a very fine spray and created almost microscopic structures in the matrix rock.

This is especially notable at the heads of the Agaete ravine (barranco de Agaete) and Mogan ravine (barranco de Mogan), where we can see horizontal basaltic lavas in their lower parts and, above, thicker material in sloping layers.

Todas aquellas negras murallas de la gran caldera, con sus crestas, que parecen almenas, con sus roques enhiestos, ofrecen el aspecto de una visión dantesca.

No otra cosa pueden ser las calderas del Infierno que visitó el florentino.

All those black walls of the great caldera, with its crests, which look like battlements, with its erect rocks, offer a Dantesque vision.
