Pico Basilé (formerly Pico de Santa Isabel), located on the island of Bioko, is the tallest mountain of Equatorial Guinea. With an altitude of 9,878 ft (3,011 m), it is the summit of the largest and highest of three overlapping basaltic shield volcanoes which form the island. From the summit, Mt. Cameroon can be seen to the northeast. Pico Basilé lies close to the city of Malabo. The very top is used as a broadcast transmitting station for RTVGE (Radio Television Guinea Ecuatorial) and microwave relay station for various communication networks.
Bioko was formed along the Cameroon line, a major northeast-trending geologic fault that runs from the Atlantic Ocean into Cameroon. This line includes other volcanic islands in the Gulf of Guinea such as Annobón, Príncipe and São Tomé, along with the massive stratovolcano of Mount Cameroon. Unlike the three other islands which are extinct volcanoes, its last eruption occurred in 1923.
Flora and fauna
Part of the Cameroon line, the flora and fauna of Pico Basilé and Bioko as a whole are similar to that of the montane regions of adjacent Cameroon and Nigeria. Multiple range restricted species occur on Pico Basilé, and one bird, the Bioko Speirops Zoterops brunneus, is wholly restricted to the volcano's higher elevations.
The peak along with the island were first discovered in 1472 by the Portuguese explorer Fernão do Pó who was seeking a path to India.
The first ascent onto the mountain were done by the English commanders from 1827 to 1828 under the Owen expedition. Its first official ascent was made in 1839 by the British John Beecroft who was later governor of the island that was once Fernando Poo, now Bioko.
