The Andes mountain chain is the southern extension of the Sierra Nevada chain through Mexico and Central America, which is, in turn the southern extension of the Rocky Mountain chain from Alaska to the Mexican border. The Andes is a magnificent series of high mountains that enters Colombia and spreads southwards through Ecuador and Peru all the way to southern Patagonia. The map is double-sided, with the Northern Andes on one side and the other side divided into two side-by-side maps portraying the Central Andes and the Southern Andes.
