Chimborazo
The peak of Chimborazo is the farthest point from the center of the Earth. This is due to the Earth bulging out at the equator and Chimborazo being located just one degree south of the equator. Mount Everest is 28° north of the equator. Thus Chimborazo is 2.1 kilometres farther from the Earth's center than Everest. Chimborazo is 73.5 metres higher than the highest mountain in North America. Chimborazo is often associated with the nearby volcano Cotopaxi, although the two volcanoes have completely different structures.
Tulcán Canton
Most of the population of the canton is in the Andes, especially in the city and surroundings of Tulcán, but the land area stretches into the Andes foothills to the west. Tulcan has the highest elevation of any city in Ecuador, above sea level. The northern limit of the canton is the border with Colombia with the most important land passage between the two countries at Rumichaca Bridge.
