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. Thus, the map coverage focuses on the Andes themselves, rather than on all of South America. All of Colombia and Peru are shown, most of Bolivia, all of Chile, and the Patagonian portion of Argentina except for the southern portion of Tierra del Fuego. The importance of this map is that it focuses on the highland areas of the continent, where much of the population lives. Bogota, Medellin, Quito, Lima, Arequipa, La Paz, Santiago, Talca, and Punta Arenas are all located along the spine of the Andes. So are the Torres del Paine peaks, the Montt Glacier, and numerous volcanoes, touristic sites, and twisting mountain roads.
