The Montaña Blanca ("white mountain") is a mountain on the Canary Island of Tenerife . Its flat summit on the eastern flank of Pico del Teide towers over the edge of the Las Cañadas basin with a height of 2748 m . This makes the Montaña Blanca the third highest peak on Tenerife after the Pico del Teide (3718 m) and the Pico Viejo (3135 m).
Emergence
The Montaña Blanca is a flank volcano of the Pico del Teide, whose name is due to the beige color of the light pumice stone on its surface. It was created by volcanic processes that took place around the year 50 BC. Played in three phases. Initially, phonolithic lava with a volume of about 0.022 km³ emerged from an eruption fissure system running from west-northwest to east-southeast on the eastern flank of Pico del Teide. The eruption then went into an explosive, Subplinian phase of magnitude 4 on the volcanic explosivity index . Within 7 to 11 hours, phonolithic pumice stone and ash (approx. 0.25 km³ DRE ) fell from a 15 km high eruption column towards the northeast and covered an area of at least 40 km². In a third phase, about 0.025 km³ of lava emerged, and today's lava dome was formed . The Subplinian eruption of the Montaña Blanca is the only known explosive eruption in the volcanic complex of Pico del Teide and Pico Viejo.
Ascent
The Montaña Blanca is an excellent panoramic mountain. It can be climbed without any problems via a branch from the Sendero hiking trail no. 7 (from the parking lot at the TF-21 below the Montaña Blanca to the summit of the Teide). The tour can also start at the El Portillo visitor center and then takes you either via paths no. 1 and no. 6 or no. 1 and no. 22 to sendero no. 7. This runs along the Montaña Blanca through a pumice stone field on which there are numerous black lava balls - the Huevos del Teide (Teide eggs).
