3 Facts About Mount Kilimanjaro
Often referred to as the “Roof of Africa,” Mount Kilimanjaro is one of Earth’s most iconic and stunning features. It is a single, massive mountain that rises from the plains, located entirely within Tanzania and just south of the Kenya-Tanzania border. It is significant to geologists, biologists, and explorers, and is not just a physical challenge, but can take you through virtually all the world’s climate zones.
Kilimanjaro National Park preserves the massif, which has been a UNESCO World Heritage site since 1987, meaning this unique cultural and biological heritage can be preserved for future generations. Three things that illustrate its importance to the world are its size, volcanic history, and its unique environmental niche.
1. The Tallest Mountain In The World That Stands On Its Own
Kilimanjaro has a unique and impressive geographical title: it is the highest mountain in the world that is not part of a mountain range. This means that it is not part of a mountain range like the Himalayas or the Andes. Instead, it rises up from a flat plateau base. Because it stands out so much, its height is even more impressive and easy to see from hundreds of miles away on a clear day.
Unmatched Height and Importance
The highest point on the mountain is Uhuru Peak on the Kibo cone. It is 5,895 meters (19,341 feet) above sea level, making it the highest point on the entire African continent and one of the Seven Summits (the highest mountains on each continent). Its “free-standing” status, on the other hand, refers to its prominence, which is a measure of how high a mountain is compared to the lowest contour line that surrounds it and has no higher peak. Kilimanjaro’s prominence is almost the same as its height, which is about 4,900 meters (16,100 feet) above its base on the plateau.
The mountain appears massive and solitary because of the vertical rise of the plains. This factor alone becomes a significant issue for climbers to acclimate to altitude. The mountain is a stratovolcano consisting of multiple layers of solidified ash and lava. Due to its scale, the volcano was able to attain this massive altitude without the benefit of tectonic compression, the primary force of uplift that creates a mountain range. Therefore, the challenge for climbers is not technical rock or ice climbing (it’s an extended hike), but rather the sustained risk of altitude sickness on the extended hike.
Next, the significance of Kilimanjaro’s volcanic history emerges, as its immense volcanic structure shapes much of its uniqueness.
Mount Kilimanjaro is not just one peak, but rather a gigantic, dormant stratovolcano made up of three distinct volcanic cones that formed millions of years ago. The volcano’s massive scale and shape are largely due to this distinct geological structure.
2. The Three Volcanic Peaks
The Kilimanjaro caps feature three volcanic cones: Kibo, Mawenzi, and Shira. Kibo is, by far, the youngest and tallest of the three cones. It has the highest ground on the mountain: Uhuru Peak. Kibo is believed to be a dormant volcano – meaning it could potentially erupt again, but has not erupted for the past 150,000 to 200,000 years. However, Kibo shows strong signs of life, like the inner cone and steaming ash pit within the large caldera. The dormant formation is one of the main reasons the peak has its impressive shape and height.
Mawenzi, however, is not alive; this cone has washed away more than Kibo because it is older. Mawenzi is 5,149 meters (16,893 feet) tall, and the very jagged cragginess shows how much it has been eroded.
The third cone, Shira, is the lowest and oldest of the three. This part of the mountain fell apart during the last few million years, resulting in a broad plateau on the western side of the mountain, at about 4,005 meters (13,140 feet) high. During the last several million years, the massive tectonic forces that shaped the Great Rift Valley have affected this area of East Africa, and the very size of this volcano serves as evidence of these forces..
3. A trip through five different ecological zones
People often say that climbing Mount Kilimanjaro is like going from the Equator to the Arctic in just a few days. This is because the mountain is so high and far away from the equator that it creates a unique weather pattern, where different ecosystems are stacked on top of each other like cake layers. Climbers go through five major ecological zones on their way from the base to the top. Each zone has its own climate, plants, and animals.
The Five Zones of Climate
The journey will begin in the Cultivation Zone, which is found lower down the slopes, between 800 and 1,800 meters (2,600 and 5,900 feet). The fertility of the volcanic soil in this zone means that some farmland will be found here, and some minor grasslands. Climbers reach the summit when they cross into the Rainforest Zone, which is found between 1,800 to 2,800 meters or 5,900 to 9,200 feet. This densely grown, humid region gets large amounts of rain and large populations of animals, such as several species of primates and plants that only exist here.
This forest is found below the Heath and Moorland Zone. It is located between the altitudes of 2,800 and 4,000 meters (9,200 and 13,100 feet). This zone has cooler and drier air, which results in interesting, weird-looking plants such as the giant groundsel and giant lobelia. These plants are adapted to the dramatic fluctuations in temperature between day and night. Finally, the next zone is the Alpine Desert Zone, which is located between the altitudes of 4,000 and 5,000 meters (13,100 and 16,400 feet). This is a harsh, rocky place that receives very little rain and has few plants. It resembles the look of Mars.
The Arctic Zone (5,000 meters or 16,400 feet and above) is the last part of the summit. It is a barren, frozen world made up mostly of rock, ice, and the last glaciers. Here, the temperature drops a lot, often well below freezing, and the air gets very thin.
The fact that Kilimanjaro goes through so many different climates in such a short amount of time makes it a unique and dramatic experience. It lets people see how the environment changes quickly. Unfortunately, this highest zone is also the most fragile. The famous ice cap is quickly melting, which is a clear sign of global climate change, and it is expected to be gone in a few decades.
