Mount Kenya is the highest mountain in Kenya and the second-highest in Africa, after Kilimanjaro. The highest peaks of the mountain are Batian (5,199 m), Nelion (5,188 m) and Point Lenana (4,985 m). Mount Kenya is located in central Kenya, just south of the equator, around 150 km north-northeast of the capital Nairobi. Mount Kenya is the source of the name of the Republic of Kenya. Mount Kenya is a stratovolcano created approximately 3 million years after the opening of the East African rift.
Before glaciation, it was 7,000 m high. It was covered by an ice cap for thousands of years. This has resulted in very eroded slopes and numerous valleys radiating from the centre. There are currently 11 small glaciers. The forested slopes are an important source of water for much of Kenya. There are several vegetation bands from the base to the summit. The lower slopes are covered by different types of forest. Many alpine species are endemic to Mount Kenya, such as the giant lobelias and senecios and a local subspecies of rock hyrax. An area of 715 km2 around the centre of the mountain was designated a National Park and listed as a UNESCO World Heritage Site in 1997. The park receives over 16,000 visitors per year.
Mount Kenya National Park, established in 1949, protects the region surrounding the mountain. Currently the national park is within the forest reserve which encircles it. In April 1978 the area was designated a UNESCO Biosphere Reserve. The national park and the forest reserve, combined, became a UNESCO World Heritage Site in 1997.
Mount Kenya is a stratovolcano that was active in the Plio-Pleistocene. The original crater was probably over 6,000 m high; higher than Kilimanjaro. Since it became extinct there have been two major periods of glaciation, which are shown by two main rings of moraines below the glaciers.
The rocks that form Mount Kenya are mainly basalts, rhomb porphyrites, phonolites, kenytes and trachytes. Kenyte was first reported by Gregory in 1900 following his study of the geology of Mount Kenya. The peaks of Mount Kenya are almost all from a volcanic origin. The majority of the peaks are located near the centre of the mountain. These peaks have an Alpine appearance due to their craggy nature. Typically of Alpine terrain, the highest peaks and gendarmes occur at the intersection of ridges. The highest peaks are Batian (5,199 m), Nelion (5,188 m) and Point Lenana (4,985 m). Batian and Nelion are within 250 m of each other, separated by the Gate of the Mists gap (5,144 m). Coryndon Peak (4,960 m) is the next highest, but unlike the previous peaks it does not form a part of the central plug.
