Lake Titicaca


This map of Lake Titicaca was made by Rafael E. Baluarte, cartographer of the Geographical Society of Lima, for a presentation to the society in December 1891 of a monographic study of the lake by Dr. Ignacio La Puente. It is based on surveys and explorations of the lake and its environs by the British diplomat and explorer Joseph Barclay Pentland (1797–1873), the Italian-Peruvian geographer and naturalist Antonio Raimondi (1826–90), the Swiss-born naturalist Louis Agassiz (1807–73), and others. The map shows ancient ruins, mines, the sites of noteworthy battles, roads, and railroads. Depths in the lake are indicated in meters. Relief is shown by hachures. The prime meridian is Paris, where the map was engraved. Located partly in Peru and partly in Bolivia, Titicaca is the largest freshwater lake in South America. At 3,810 meters above sea level, it is the highest of the world's large lakes. It covers 8,300 square kilometers, and extends in a northwest-to-southeast direction for a distance of 190 kilometers. At its widest point the lake is 80 kilometers across. The lake averages between 140 and 180 meters in depth, and reaches its greatest recorded depth of 280 meters off Isla Soto in its northeastern corner. (This map shows a depth of 256.49 meters at a location just east of the island.) More than 25 rivers flow into Lake Titicaca. Archeological ruins and other evidence indicate that different peoples have lived around the lake continuously since as early as 10,000 BC. These peoples have included the Pukara, Tiwanaku, Colla Lupaka, and Inca.
