"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. Unlike most African snow peaks, the Ruwenzori is not of volcanic origin but is a gigantic horst of six separate glaciated masses, reaching a high point in Mount Stanley at Margherita Peak (16,795 feet [5,119 m]). The Ruwenzori Range's largest mountains are separated by passes and deeply cut river valleys that all eventually drain into the Semliki River. The mountain summits are often hidden in cloud cover, created periodically by moist airstreams from the Atlantic and Indian oceans. 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 by Maya Bracher when she traveled to Africa from October 26, 1970 to end of March 1971. She was on assignment for Eliot Elisofon when he wrote, produced, and directed a four-hour television series for Group W (Westinghouse Broadcasting Company) titled Black African Heritage (1973). The series was divided into four segments, lasting 50 minutes each: The Congo, The Bend of the Niger, The Slave Coast, and Africa's Gift.
