Answer:
Lake Titicaca
Step-by-step explanation:
Lake Titicaca is actually the highest navigable lake in the world, which means that it's a lake that ships and boats can sail on. It's located in the Andes Mountains and is shared by Peru and Bolivia. It's quite high up in the mountains, at an altitude of over 12,500 feet (or 3,800 meters) above sea level! It's also a pretty big lake, covering an area of over 3,200 square miles (or 8,300 square kilometers), and it's the second largest lake in South America.
