Tanzania - 20007; Awarded Highly Conmended Audubon Society; The Ngorongoro Crater was formed over 2 million years ago when the Ngorongoro volcano blew apart and left a 12 mile wide flat plain rimed with steep walls that soar 2,000 feet. Part of the Serengeti ecosystem, Cheetahs are among several breeds of mammalian predators that live in the crater. This Cheetah casually dips his bloody tongue into the clear stream after devouring its prey.
