Ecuador Republic in South America

Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about 1,000 kilometres (620 mi) west of the mainland. The capital city is Quito, which is also the largest city.

Andes mountain range running along the tu mamide of South America

The Andes or Andean Mountains are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. This range is about 7,000 km (4,300 mi) long, about 200 to 700 km wide, and of an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

Cayambe, which has a permanent snow cap, is a Holocene compound volcano which last erupted in March 1786. [1] At 4,690 metres (15,387 ft) on 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 volcano and most of its slopes are within the Cayambe Coca Ecological Reserve.

Holocene The current geological epoch, covering the last 11,700 years

The Holocene is the current geological epoch. It began approximately 11,650 cal years before present, after the last glacial period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch.

Equator Intersection of a spheres surface with the plane perpendicular to the spheres axis of rotation and midway between the poles

An equator of a rotating spheroid is its zeroth circle of latitude (parallel). It is the imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles.

Cayambe Coca Ecological Reserve nature reserve in Ecuador located along the Equator about 38 km (24 mi) from Quito

Cayambe Coca National Park is a national park in Ecuador located along the Equator about 38 km (24 mi) from Quito. The park encompasses an area of 4,031.03 km2.

Cayambe was first climbed by British adventurer Edward Whymper and his two Italian guides and companions Jean-Antoine Carrel and Louis Carrel in 1880, [2] and it remains a favorite of mountaineers today.

Edward Whymper British mountaineer

Edward Whymper was an English mountaineer, explorer, illustrator, and author best known for the first ascent of the Matterhorn in 1865. Four members of his climbing party were killed during the descent. Whymper also made important first ascents on the Mont Blanc massif and in the Pennine Alps, Chimborazo in South America, and the Canadian Rockies. His exploration of Greenland contributed an important advance to Arctic exploration. Whymper wrote several books on mountaineering, including Scrambles Amongst the Alps.

Jean-Antoine Carrel Italian mountain climber and guide

Jean-Antoine Carrel was an Italian mountain climber and guide. He had made climbs with Edward Whymper and was his rival when he attempted to climb the Matterhorn for the first time. Whymper ultimately succeeded in making the mountain's first ascent in July 1865 while Carrel led the party that achieved the second ascent three days later. Carrel was in the group that became the first Europeans to reach the summit of Chimborazo in 1880. He died from exhaustion when guiding a party on the south side of the Matterhorn.

Mountaineering sport of mountain climbing

Mountaineering is the set of activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, hiking, skiing, and traversing via ferratas. Indoor climbing, sport climbing and bouldering are usually considered mountaineering as well.

Cayambe's peak is the point of Earth's surface farthest from its axis; thus it rotates the fastest as Earth spins. [3]

Earth Third planet from the Sun in the Solar System

Earth is the third planet from the Sun and the only astronomical object known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.

Licancabur is a stratovolcano on the border between Bolivia and Chile, south of the Sairecabur volcano and west of Juriques. Part of the Andean Central Volcanic Zone, it has a prominent, 5,916-metre (19,409 ft)-high cone. A 400-metre (1,300 ft) summit crater containing Licancabur Lake, a crater lake which is among the highest lakes in the world, caps the volcano. Three stages of lava flow emanate from the volcano, which formed on Pleistocene ignimbrites.

Sangay active stratovolcano in central Ecuador

Sangay is an active stratovolcano in central Ecuador. It is the most active volcano in Ecuador, despite erupting only three times in recorded history, because the eruption that started in 1934 is still ongoing. It exhibits mostly strombolian activity. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity. Sangay's approximately 500,000-year-old history is one of instability; two previous versions of the mountain were destroyed in massive flank collapses, evidence of which still litters its surroundings today.

Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name, which is Spanish for 'exploder' or 'ripper'. Since 1541 it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. Its most recent eruption began in 2008 and is ongoing as of July 4, 2017. The largest historical eruption occurred in 2002. During that eruption the plume from the volcano reached a height of 17 km and pyroclastic flows went up to 7 km from the cone.

Sincholagua is an inactive volcano located in Ecuador 17 km (11 mi) northeast of Cotopaxi Volcano and 45 km (28 mi) southeast of Quito. It is the 12th highest peak in the country at 4,899 m (16,073 ft) but also one of the lesser known ones. The name of the mountain comes from the indigenous language Quichua and means "strong above". Due to its close proximity to Cotopaxi, the second highest peak in Ecuador and the most popular volcano, it is far less frequently visited compared to other mountains in the country. It has a sharp peak and at one point had glacial cover year round, but all of the glaciers melted a few decades ago. However, snow can still be seen on the peak since there is there is sometimes heavy snowfall at the summit.
