Chimborazo
The summit of Mount Everest is higher above sea level, but the summit of Chimborazo is widely reported to be the farthest point on the surface from Earth's center, with Huascarán a very close second. The summit of the Chimborazo is the fixed point on Earth that has the utmost distance from the center – because of the oblate spheroid shape of the planet Earth, which is "thicker" around the Equator than measured around the poles. Chimborazo is one degree south of the Equator and the Earth's diameter at the Equator is greater than at the latitude of Everest ( above sea level), nearly 27.6° north, with sea level also elevated. Despite being lower in elevation above sea level, it is from the Earth's center, farther than the summit of Everest ( from the Earth's center). However, by height above sea level, Chimborazo is not the highest peak of the Andes.
Tourism in Ecuador
Quilotoa it is a water-filled boiler and the westernmost volcano in the Ecuadorian Andes. The 3 km wide boiler was formed by the collapse of this dacite volcano following a catastrophic eruption 800 years ago, which produced pyroclastic flows and lahars that reached the Pacific Ocean, and spread in the air a deposit of volcanic ash along the northern Andes. The boiler has accumulated a depth of 250 m crater lake, which has a greenish color as a result of dissolved minerals. Vents are on the bottom of the lake and hot springs occur on the eastern flank of the volcano.
