Geology of Mount Elgon, Uganda & Kenya: a giant pre-rift volcano.
The free-standing Mount Elgon Volcano is located north of Lake Victoria and cuts across the international boundary between Uganda and Kenya. The dome-shaped profile with a gentle slope of only 40 is typical of a deeply eroded shield volcano. Mount Elgon is the only example of the pre-rift volcanism associated with the Gregory Rift, the eastern branch of the East African Rift System (EARS), which has a sufficiently large cone to justify being protected in a park or reserve. Two national parks are recognised, one in Uganda, which this contribution is largely based on, and one in Kenya.
