Viewpoint Caldera de Los Marteles

Formation of the Los Marteles Crater, which extends before one in a southerly direction, is due to an explosive type of volcanism, produced by the interaction of water-magma. As a consequence we encounter an elliptical shaped crater, 500 meters in diameter and 80 meters deep. Its geological age corresponds to the ‘Recent Cycle’ and it is a contemporary of the Bandama Crater, the Pico de Osorio and of the volcanic whole of Lomo Magullo. Given that it forms a closed water basin, its bed is very suitable for agriculture, thus seeing livestock grazing in the same is not an unusual sight.
The Tenteniguada Crater can be sighted right on the opposite side, in a northeasterly direction, with this crater, of an erosive origin, representing the headland of the tributary ravines of the San Miguel Ravine, which tailwater from the same turns into the Telde. In this sector dismemberment of the Central Massif has uncovered the lava plugs or chimneys of the ‘Roque Nublo Cycle’ eruptions: Roques de Tenteniguada, Roque del Pino and Roque Saucillo.
It is in this spectacular landscape that we also encounter capricious forms due to the erosion.
