The World's Largest Intact Volcanic Caldera

This is the three minute postcard of the Ngorongoro Crater, the world's largest intact volcanic caldera...

Between two and three million years ago one of the largest mountains in what is now Tanzania collapsed in on itself during a powerful volcanic explosion. The resulting crater would become one of the most unique wildlife environs on the African continent. At the moment of the crater's creation the animals and plants within site of the explosion would have been totally wiped out. The entire area had to begin again; life would go on to recolonize an almost perfectly circular volcanic bowl with a rich tapestry of various species.

Today the Ngorongoro Crater is one the most visited safari sites in Africa, a true gem in Tanzania.
