Congolese members of Eliot Elisofon's trekking expedition, Ruwenzori Mountains, Congo (Democratic Republic)

"Lying slightly north of the Equator, the Ruwenzori Range has a maximum breadth of 30 miles (50 km) and extends south-north for 80 miles (130 km) between Lake Edward and Lake Albert. The Ruwenzori Range falls steeply westward to the Western Rift Valley, while its descent to the east is more gradual, leading to the uplands of the western part of Uganda. The Ruwenzori Range's largest mountains are separated by passes and deeply cut river valleys that all eventually drain into the Semliki River. While trekking through this ecoregion, you'll move through several types of vegetation. In the low elevations of the Virungas, forests of bamboo provide cover for mountain gorillas. Moving up the mountain slopes, you will find yourself dwarfed by giant heather plants covered in lichens and mosses. As you climb close to the snowline, you'll reach montane grasslands full of giant senecio and lobelia plants, as well as abundant swamps. These unusual moorlands are quite rare in the world--found only in east and central Africa, New Guinea, and the northern Andes." This photograph was taken when Eliot Elisofon traveled to Africa from early March 1951 to July 1951.
