Ngorongoro Conservation Area is in northern Tanzania. It’s home to the vast, volcanic Ngorongoro Crater and “big 5” game (elephant, lion, leopard, buffalo, rhino).
Huge herds of wildebeests and zebras traverse its plains during their annual migration. Livestock belonging to the semi-nomadic Maasai tribe graze alongside wild animals. Hominin fossils found within the Olduvai Gorge go back many years.
The jewel in Ngorongoro’s crown may be a deep, crater, the most important unflooded and unbroken caldera within the world. About 20kms across, 600 meters deep, and 300 sq km in area, the Ngorongoro Crater may be a breathtaking natural wonder.
Conservation Area is a protected area and a World Heritage Site located 180 km (110 mi) west of Arusha within the Crater Highlands area of Tanzania. the world is known as after Crater, an outsized volcanic caldera within the world.
The conservation area is run by the Conservation Area Authority, an arm of the Tanzanian government, and its boundaries follow the boundary of the Ngorongoro Division of the Arusha Region.
The 2009 Wildlife Conservation Act placed new restrictions on human settlement and farming within the Crater, displacing Maasai pastoralists, most of whom had been relocated from their ancestral lands to the north when the British colonial government established Serengeti park in 1959.
The name of the crater has an onomatopoeic origin; it had been named by the Maasai pastoralists after the sound produced by the cowbell. supported fossil evidence found at the Olduvai Gorge, various hominid species have occupied the world for 3 million years.
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 meters (2,000 feet) deep and its floor covers 260 square kilometers (100 square miles).
Estimates of the height of the original volcano range from 4,500 to 5,800 meters (14,800 to 19,000 feet) high. 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. The volcano was active from about 2.45 to 2 million years ago.
The volcanic eruptions like that of Crater, which resulted in the formation of Ngorongoro Crater in Tanzania, were very common. Similar collapses occurred in the case of Olmoti and Empakaai, but they were much smaller in magnitude and impact.
