Kitum Cave is located in Mount Elgon National Park, Kenya. In the 1980s, two European visitors contracted Marburg virus disease there. It is one of five named “elephant caves” of Mount Elgon where animals, including elephants, “mine” the rock for its sodium-rich salts.
Kitum Cave is a non-solutional cave developed in pyroclastic (volcanic) rocks (not, as some have presumed, a lava tube).
