Pico de Teide and the Cañadas in spring and summerUnless otherwise noted the following photos were taken by Jürg Alean as far back as 1975, but also in more recent years. These images center on Pico de Teide, highest peak in the Atlantic Ocean (3715m.a.s.l.) and the the dramatic 10 x 17 km Las Cañadas caldera from which it rises. Nothing changed since Pliny the Elder (AD 23-79) wrote about Tenerife: «Ninguaria, which has received that name from its perpetual snows wrapped in clouds». | |||
 The Pico de Teide - Pico Viejo edifice seen from Cañadas bottom. Green bush of Teide broom (Spartocytisus supranubius) in the foreground. |  Huge bomb on Montaña Blanca (2743m), the main satellite vent of the Pico de Teide - Pico Viejo complex. Montaña Blanca is a phonolite dome 300m high. |  Teide violets (Viola cheiranthifolia), a rare endemic plant of Tenerife, at an altitude of more than 3000m.a.s.l. |  Small snow penitentes below El Piton, Teide's youngest summit vent, 1370m above the caldera floor. Its lavas cover most of Teide's cone. |
 Pico Viejo seen from Teide's summit. Against the inner southern wall of the summit caldera rests a large, flat-topped, layered block. A pit, 65 m deep, lies in the SW part. |  Wall of Teide's summit crater. Pico de Guajara (2717m) in the left background: it is the top of the caldera wall, visible for 27 km in the SW, S and E but absent at Nord. |  View from Teide summit towards NE. Two summit collapse phases truncated the summit and formed paired scarps. |  View from Teide towards Parador and Pico de Guajara: Ucanca caldera (1.02 Ma, on the left) and Guajara caldera (0.57 Ma, on the right). |
 Teide at sunset seen from Montaña la Negrita. |  Seen from the summit crater: Teide's shadow at sunset and the "Venus belt" (the pinkish coloured band above the horizon). |  Teide from Pico de Guajara. Note the V-shaped gulleys on the S flank and hydrothermal alteration (white) of the top. |  "La Tarta" pyroclastic deposits. Basaltic and phonolitic magmas were erupted in sequence (photo Marco Fulle). |
