Lake Titicaca

Lake Titicaca (right of center) is a lake located on the border of Bolivia and Peru. It sits at 3,812 m (12,500 ft) above sea level, making it one of the highest commercially navigable lakes in the world.

By water volume it is also the largest lake in South America. Lake Titicaca is fed by rainfall and meltwater from glaciers on the sierras that abut the Altiplano.

The lake is located at the northern end of the endorheic Altiplano basin, high in the Andes. The western part of the lake lies within the Puno Region of Peru, and the eastern side is located in the Bolivian La Paz Department.

The lake is composed of two nearly separate sub-basins that are connected by the Strait of Tiquina which is 800 m (2,620 ft) across at the narrowest point.

The larger sub-basin, Lago Grande (also called Lago Chucuito) has a mean depth of 135 m (443 ft) and a maximum depth of 284 m (932 ft).

The smaller sub-basin, Wiñaymarka (also called Lago Pequeño, “little lake”) has a mean depth of 9 m (30 ft) and a maximum depth of 40 m (131 ft).[5] The overall average depth of the lake is 107 m (351 ft).

    How was lake Titicaca formed? Is it the top of a huge volcano??

    Titicaca is a geological wonder, formed sixty million years back; from the water deposited by 25 incoming rivers which carry the water from melted glaciers of the Andes.
