Tanzania’s Ngorongoro Crater The 8th Wonder of the Natural World – Twenty million years ago, a volcano that never had a chance to be named led to the creation of the most beautiful and exciting places of earth for travelers (safari-goers). At that time, the landscape of Eastern Africa was rich with geological activity, pressures had been building for tens of centuries along two tectonic plates, reaching a point where a series of earthquakes, splits and faults resulted in the formation of what is now known as the Great Rift Valley.
Over the millennia, this activity also fueled volcanic eruptions creating massive mountains including Mount Kilimanjaro, Mount Meru and the other unnamed mountain. All the three mountains were believed to be the size of what Mount Kilimanjaro is today, Mount Meru was later shortened by the later volcanic activity.
Today, if you travel to Arusha by road from Kenya via the Namanga border, you can follow the slopes on either side and picture the huge part that is now missing. The third mountain that was formed about three million years ago, the volcanic activity continued until about 2.5 million years ago, when the cone became so heavy that it could no longer support its own weight. It fell upon itself causing a massive caldera. There are many calderas around the world but most were damaged upon creation, with one or more sides destroyed. Others were flooded and have become spectacular natural lakes. But in Tanzania, this caldera remains a complete bowl.
The lake on the floor of the Ngorongoro crater is 102-square-mile floor and is large enough to support a variety of life, but it does not flood.
The ongoing volcanic eruptions during this period frequently sent towering plumes of ash into the air, as the ash settled. I served two important purposes, first it created the rich, fertile soil that eventually led to an ecosystem that supports more than thirty thousand resident mammals and countless other creatures in the crater alone. Secondly, it preserved important archeological artifacts such as the remains of Paranthropus boisei (previously known as East African Man) at Olduvai Gorge.
Today’s Ngorongoro Crater remains as amazing as it must have been at its formation (birth) and it is home to almost every species of African mammal. It is possible to see the Big Five (lion, leopard, elephant, buffalo and rhinos) in a single game drive.
In 1997, two rhinoceros were introduced to the crater alongside the indigenous one who numbers had declined to twelve, only two of which were adult males. This was done in hopes of augmenting the species’ gene pool, fortunately due to the limited access down the thousand-foot walls to the crater’s floor and strict management by the Ngorongoro Conservation Area Authority, poaching is not as a serious problem in Ngorongoro.
It is believed that hippopotami migrated to the crater hundreds of years ago from Lake Manyara traveling up the Great Rift Valley Escarpment, through what is now the village of Karatu to the rim of the crater and then back to the floor.
Today, all elephants in the Ngorongoro Crater are bulls. They make the trip in search of the rich minerals found in the grasses and the soda lake – Lake Magadi at the crater’s center. The females and calves remain at the rim which is lush with vegetation.
For predators such as the big cats, the crater is a big dinner bowl. Finding a meal in the crater is seldom a problem.
However, the limited gene pool and in-family breeding does lead to risk of devastation from disease. In the early 200s, lion population was seriously affected by sickness. Fortunately, the health of the prides has improved and they grown in number so that the balance between predator and prey continues.
Most of the mammals found in the Ngorongoro crater are year-round residents and do not join the migrations that their cousins enjoy, the story is a bit different with the birds of the region. The large flocks of lesser flamingoes that can sometimes be found in the crater travel between Lake Magadi, Lake Natron, Lake Eyasi and Lake Ndutu.
On of the animals that you will not find in the crater is the giraffe, there are differing theories as to why this is so. Many of the theories point to the lack of adequate vegetation for these browsers while others insist that the steep trails leading from the rim are impossible for the giraffe to navigate.
Tanzania’s Ngorongoro Crater The 8th Wonder of the Natural World – The Ngorongoro Conservation Area comprises the Ngorongoro Crater, two smaller craters (Empakaai and Olmoti). Eight extinct volcanoes and part of the Serengeti plains. The Ngorongoro Conservation Area, Serengeti National Park and Kenya’s Maasai Mara make up the Serengeti Ecosystem.
During the first few months of the year, depending on the rains. The animals of the Africa’s Great Migration may swing southward for enough for the herds to spend time in the conservation area.
In the early 2000’s, the crater’s lion population declined due to sickness among the pride. Fortunately, their health improved and their numbers have bounced back.
A unique aspect of the Ngorongoro Crater is that it is not only a site of interaction with wild animals with humans and domestic animals as well. For generations, the Maasai have led their herds of cattle down to the crater’s floor to graze on the mineral-rich grass.
Guests at local lodges often awake to the sounds of clanking cowbells as Maasai warriors guide their most prized possessions past the lodge and down the steep trails. It is estimated that more than fifty thousand Maasai live in the Ngorongoro Conservation Area.
The Maasai’s use of the crater goes back more than a hundred years, presently an ancient fig tree remains reserve for the Maasai and Datoga people as a spiritual place where they – like their ancestors before them. They visit this place to pray for their children and cattle.
In 1979, the United Nations Educational, Scientific and Cultural Organization (UNESCO) added the Ngorongoro Conservation Area to its World Heritage Site list. Often, the crater is referred to as the “Eighth Wonder of the Natural World”.
