Ngorongoro Crater is located in the northern part of TanzaniaEast Africa Rift Valley. It is an extinct crater with an altitude of 2,400 meters and a diameter of approximately It is 18 kilometers long and 610 meters deep. It is shaped like a large basin. The”basin” is about 16 kilometers in diameter. The”basin wall” is steep and the bottom area is 326 square kilometers. The crater is shaped like a large basin with steep”basin walls” and its shape is very similar to that of a lunar crater, making it the second largest crater in the world.

En Ge The Roengoro volcano used to be conical in shape, twice as high as it is now. 2.5 million years ago, the cone erupted for the last time, erupting all the lava, and the top of the cone collapsed into a recess, leaving only Round Table Mountain on the northwest side of the crater.

In geology, a crater formed by a volcanic eruption or collapse is called a caldera. The Ngorongoro crater is the largest of the many caldera with intact edges. Africans call it”Ngorongoro”, which means”big cave”. In 1959, someone built a rugged road leading to the ground in the crater with a total length of 3,200 meters.

12 per year After the rainy season from January to April and May of the following year, the grass in the Ngorongoro crater will appear emerald green, mixed with pink, yellow, blue and white flowers. On the fertile volcanic soil, morning glory, lupin daisy, and the rare blue alfalfa blossomed.

When the dry season comes from May to November, the inside of the crater gradually changes from green to yellow, then to light yellow-brown, then to dark brown, and animals begin to gather around the Menggai Marsh. Since 2/3 of the crater is grass, except for scattered acacia trees and exposed rocks, it is a uniform color volcano The edge of the crater isolates the inside and the outside, but the animals in the crater do not need to feed outside for survival.

grazing The zebras, wildebeest and gazelles mainly depend on the grassland. At the same time, they also become food for lions, leopards, cheetahs, hyenas, jackals, etc. These carnivores linger near the herbivore group, waiting for opportunities to snipe the outliers. Most herbivores give birth during January and February when the grass is the greenest. Carnivores also reproduce during this period in order to capture a large number of herbivore cubs for feeding by nursing mothers and weaned cubs.

also here The most concentrated place of wild animals in Africa. In the crater, there are estimated to be about 30,000 animals, including more than 50 large mammals, including lion elephants, rhinos, Hippo, giraffe, monkey, baboon, warthog, hyena and various antelopes. In addition, there are more than 200 kinds of birds, including ostriches, wild ducks, and guinea fowls.

In fact, this crater is a microcosm of the entire East African wildlife world.

most of The animals of Ngorongoro have settled in the crater for many years. In the dry season, there is still no shortage of water sources in the crater. There are two springs and two rivers-the Menggai and Longyok Rivers supply water to many marshes, and there is a shallow alkali lake-Lake Magadi, so the animals living here have The endless water of life. Lake Magadi has no exit. After long-term evaporation, the salt content in the water is very high. Under the shining of light, it will show a deep blue light. Here, only algae and shrimp crustaceans can survive in the water.

En Ge The geographical feature of the Roengorro Crater isolated from the outside world has also attracted many zoologists and other scientists to study wild animals and their unique ecosystems.
