11. Kalahari Desert's Lost City

Gates searches for a lost city in the Kalahari Desert in Africa. First discovered by circus pioneer The Great Farini in 1885, he supposedly came across the ruins of a lost city half buried in the scorching sands. Those who followed in his footsteps came up empty-handed and claimed it a hoax, while even some vanished. Today, a modern explorer launched an all new expedition which Gates joins.
