The mountain
El Pichincha (4,784 m -15,696 ft) is an active stratovolcano situated in Ecuador. The two highest peaks of the mountain are Wawa Pichincha (Hispanicized spelling Guagua Pichincha meaning child, baby or small and Ruku Pichincha (Hispanicized Rucu Pichincha meaning old person, in Kithwa rujku langage) (4,698 metres (15,413 ft)). The active caldera is in Wawa Pichincha on the western side of the mountain.
Both peaks are visible from the city of Quito and both are popular acclimatization climbs.
In October 1999, the volcano erupted and covered the city with several inches of ash. Prior to that, the last major eruptions were in 1553 and during the Plinian eruption of 1660, when about 30 cm of ash fell on the city of Quito.
In 1737 several members of the French Geodesic Mission to the Equator, including Charles-Marie de La Condamine, Pierre Bouguer and Antonio de Ulloa, spent 23 days on the summit of Rucu Pichincha as part of their triangulation work to calculate the length of a degree of latitude.
On 17 June 1742, during the same mission, La Condamine and Bouguer made an ascent of Guagua Pichincha and looked down into the crater of the volcano, which had last erupted in 1660. La Condamine compared what he saw to the underworld.
On May 24, 1822, General Sucre's southern campaign, in the context of the Spanish-America war of independence, came to a climax when patriot forces defeated the Spanish colonial army on the south-east slopes of this volcano. The engagement, known as the Battle of Pichincha, secured the independence of the territories of present-day Ecuador.
The most recent significant eruption was in August 1998. On March 12, 2000, a phreatic eruption killed two volcanologists who were working on the lava dome.
The artist
Friedrich Wilhelm Heinrich Alexander von Humboldt was a Prussian geographer, naturalist, explorer, and influential proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring.
Between 1799 and 1804, Humboldt travelled extensively in Latin America, exploring and describing it for the first time from a modern scientific point of view. His description of the journey was written up and published in an enormous set of volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use of the word cosmos from the ancient Greek and assigned it to his multi-volume treatise, Kosmos, in which he sought to unify diverse branches of scientific knowledge and culture. This important work also motivated a holistic perception of the universe as one interacting entity.
On their way back to Europe from Mexico on their way to the United States, Humboldt and his fellow scientist Aimé Bonpland stopped in Cuba for a While. After their first stay in Cuba of three months they returned the mainland at Cartagena de Indias (now in Colombia), a major center of trade in northern South America. Ascending the swollen stream of the Magdalena River to Honda and arrived in Bogotá on July 6, 1801 where they met Spanish botanist José Celestino Mutis, the head of the Royal Botanical Expedition to New Granada, staying there until September 8, 1801. Mutis was generous with his time and gave Humboldt access to the huge pictorial record he had compiled since 1783. Humboldt had hopes of connecting with the French sailing expedition of Baudin, now finally underway, so Bonpland and Humboldt hurried to Ecuador. They crossed the frozen ridges of the Cordillera Real, they reached Quito on 6 January 1802, after a tedious and difficult journey.
Their stay in Ecuador was marked by the ascent of Pichincha (above) and their climb of Chimborazo, where Humboldt and his party reached an altitude of 19,286 feet (5,878 m). This was a world record at the time, but a thousand feet short of the summit. Humboldt's journey concluded with an expedition to the sources of the Amazon en route for Lima, Peru.
At Callao, the main port for Peru, Humboldt observed the transit of Mercury. On 9 November and studied the fertilizing properties of guano, rich in nitrogen, the subsequent introduction of which into Europe was due mainly to his writings.
