Teneriffe, Peak of (usu. Ten-er-iff'; Span. Tenerife, pron. Tay-nay-ree'fay), a famous dormant volcano, the highest summit (12,200 feet) in the Canary Islands (q.v.), stands in the south-west of the island of Teneriffe or Santa Cruz. Its lower slopes are covered with forests, or laid out in meadows; but the upper ridges are wild and barren. The Peak El Piton and its two inferior neighbours, the Montana Blanco and Chahorra (9880 feet), rise from a rugged circular plain of lava debris and pumice, 7000 feet above sea-level, about 8 miles in diameter, and fenced in by an almost perpendicular wall of rock. From the crevices sulphurous vapours exhale. The wall of the crater at the top is 300 feet in diameter, and 70 deep. The colour of the whole is white. There is an ice cave at an altitude of 11,000 feet. The Peak can be seen more than 100 miles off. In 1795 and 1798 there was volcanic activity here. See works by Piazzi Smyth (1858), Olivia M. Stone (new ed. 1889), and Strettell (1890).
