Geography of Trinidad and Tobago passage. Trinidad is traversed by three distinct mountain ranges that are a continuation of the Venezuelan coastal cordillera. The Northern Range, an outlier of the Andes Mountains of Venezuela, consists of rugged hills that parallel the coast. This range rises into two peaks. The highest, El Cerro del Aripo, is high; the other, El Tucuche, reaches . The Central Range extends diagonally across the island and is a low-lying range with swampy areas rising to rolling hills; its maximum elevation is . The Caroni Plain, composed of alluvial sediment, extends southward, separating the Northern Range and Central Range. The Southern
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
