Titicaca , Bolivia and Peru

Lake Titicaca is a lake located on the border of Bolivia and Peru. It sits 3,812 m (12,507 ft) above sea level making it the highest commercially navigable lake in the world.By volume of water it is also the largest lake in South America. The origin of the name Titicaca is unknown. It has been translated as "Rock Puma", allegedly because of its resemblance to the shape of a puma hunting a rabbit, combining words from the local languages Quechua and Aymara, and as well as translated as "Crag of Lead." Locally, the lake goes by several names. Because the southeast quarter of the lake is separate from the main body (connected only by the Strait of Tiquina), the Bolivians call it Lago Huiñaymarca (Quechua: Wiñay Marka) and the larger part Lago Chucuito. In Peru, these smaller and larger parts are referred to as Lago Pequeño and Lago Grande, respectively. -Wikipedia-
