Cayambe or Volcán Cayambe is a volcano in Ecuador, in the Cordillera Central, a range of the Ecuadorian Andes. It is located in Pichincha Province, some 700NaN0 northeast of Quito. It is the third-highest mountain in Ecuador, at an elevation of 57900NaN0 above sea level.
Cayambe, which has a permanent snow cap, is a Holocene compound volcano which last erupted in March 1786.[1] At 4690m (15,390feet), its south slope is the highest point in the world crossed by the Equator, and the only point on the Equator with snow cover. The ice cap covers an area of about 220NaN0 and there are glaciers on the eastern flank descending to about 4400-2NaN-2, whereas those on the drier western flank reach about 4700-2NaN-2.[2] The volcano and most of its slopes are within the Cayambe Coca Ecological Reserve.[3]
Cayambe was first climbed by British adventurer Edward Whymper and his two Italian guides and companions Jean-Antoine Carrel and Louis Carrel in 1880.[4] They made first ascents of most of the volcanoes in Ecuador. Cayambe remains a favorite of mountaineers today. The main route runs through a much-fissured terrain of moderate inclination, and only in its final part does the slope increase to 45°. There is a formidable bergschrund to cross at about 5500-2NaN-2. On the final stages, there are many cracks and seracs to be overcome, and there are extensive views from the summit.[5]
Cayambe was considered especially beautiful by Alexander von Humboldt, whose writings in turn inspired Frederic Edwin Church to paint the peak, setting the stage for his painting The Heart of the Andes.[6]
Cayambe's peak is the point of Earth's surface farthest from its axis; thus, it rotates the fastest as Earth spins.[7]
