Chile due to the folding of the rocks, forming the current relief. The Chilean relief consists of the central depression, which crosses the country longitudinally, flanked by two mountain ranges that make up about 80% of the territory: the Andes mountains to the east-natural border with Bolivia and Argentina in the region of Atacama and the Coastal Range west-minor height from the Andes. Chile's highest peak is the Nevado Ojos del Salado, at 6891.3 m, which is also the highest volcano in the world. The highest point of the Coastal Range is Vicuña Mackenna, at 3114 meters, located in the Sierra
Volcanic Seven Summits Although Aconcagua, the highest peak in South America and the highest peak in the western hemisphere, does have a volcanic origin, its current high point is due to geological processes rather than being strictly volcanic. Due to this, Aconcagua is not considered to be a volcano on its own, at least not as a member of Volcanic Seven Summits. Topographic maps of the Argentina and Chile border region which contains the highest peaks suffer from poor accuracy, with elevation errors exceeding in many cases. However, the current consensus based on the most recent measurements places Ojos del Salado as the
