Ngorongoro Crater in Tanzania, Africa, was once a volcano larger than Mt. Kilimanjaro, and about 3 million years ago (who’s counting?) a series of large eruptions occurred causing the center to cave in on itself forming a vast caldera ten miles wide. The floor is 1500 feet below the rim of the crater, and on this 80 mile area live 20,000 animals of all kinds. Here we see on solitary tree hugging a piece of earth. The water seen is a salt water lake created by leeching of the mineral content in land and rocks.
