Lake Titicaca

A very classic geography question: What’s the world’s highest located navigable lake, and where is it?
.
It’s Lake Titicaca, on the border of Peru&Bolivia at 3812 m, also being the largest lake of South America, contrary to Lake Dead Sea at -430m below sea level on Israel, Palestine & Jordan
.
According to the legends of local Quechua&Aymara groups that live together in here, it’s the birthplace of their ancestors, the very first Inkas, sent by their father&creator, the Sun, to the Sun Island on the lake.
