Rwanda: Visoke Volcano Lake
Mount Visoke (also Bisoke) is an active volcano in the Virunga Mountains of the Albertine Rift, the western branch of the East African Rift. It straddles the border of Rwanda and the Democratic Republic of the Congo, but the summit is located in Rwanda. It is located approximately 35 km northeast of the town of Goma and adjacent Lake Kivu.
Bisoke, like all of the peaks in the Virunga Mountain Range, is a volcano created by rift action on the forming divergent boundary of the East African Rift which is slowly bisecting the African plate. The mountain reached a height of 3,711 metres (12,175 ft) before becoming extinct. Bisoke has the largest crater lake of the range, a 450-m-wide lake in the summit crater.
An eruption at Mugogo volcano in 1957 formed two small cones on the north flank, 11 km from the summit.
The mountain is located within Rwandan Volcanoes National Park and Congolese Virunga National Park. The steep slopes of the peak are densely covered with equatorial rainforest and alpine meadows. The summit does not gather snow, but is often shrouded in fog.
