NGORONGORO CRATER - TANZANIA - GARDEN OF EDEN
Any Northern Safari in Tanzania is likely to end with the piece de la resistance known as the Ngorongoro Crater. This deep calderon of an anicent volcano is located in the Ngorongo Conservation Area. Some consider the crater to be the most remarkable landmark in all of Africa. Like no place on earth it is known for its diverse eco-systems and variety of animal life typical of an African safari.I turn to Wiki for more detail. The main feature of the Ngorongoro Conservation Authority is the Ngorongoro Crater, the world's largest inactive, intact, and unfilled volcanic caldera. The crater, which formed when a large volcano exploded and collapsed on itself two to three million years ago, is 610 metres (2,000 feet) deep and its floor covers 260 square kilometres (100 square miles). Estimates of the height of the original volcano range from 4,500 to 5,800 metres (14,800 to 19,000 feet) high.[10][11][12] The elevation of the crater floor is 1,800 metres (5,900 feet) above sea level. The Crater was voted by Seven Natural Wonders as one of the Seven Natural Wonders of Africa in Arusha, Tanzania in February 2013.
Approximately 25,000 large animals, mostly ungulates, live in the crater. Large animals in the crater include the black rhinoceros (Diceros bicornis), the local population of which declined from about 108 in 1964-66 to between 11-14 in 1995, the African buffalo or Cape buffalo (Syncerus caffer), and the hippopotamus (Hippopotamus amphibius).[19] There also are many other ungulates: the blue wildebeest (Connochaetes taurinus) (7,000 estimated in 1994), Grant's zebra (Equus quagga boehmi) (4,000), the common eland (Taurotragus oryx), and Grant's (Nanger granti) and Thomson's gazelles (Eudorcas thomsonii) (3,000).[19] Waterbucks (Kobus ellipsiprymnus) occur mainly near Lerai Forest.[19] There are no topis (Damaliscus lunatus), oribis (Ourebia oribi), or crocodiles (Crocodylus niloticus).[9] Impala (Aepyceros melampus) are absent because the open woodland they prefer does not exist.[1] Giraffe also are absent, possibly because of a lack of browse species.[1] Tanzanian cheetah (Acinonyx jubatus raineyii), East African wild dog (Lycaon pictus lupinus), and African leopard (Panthera pardus pardus) are rarely seen.
