Mount Stanley, part of the Ruwenzori Range on the border between the Democratic Republic of the Congo and Uganda, in east- central Africa. Stanley contains 9 of the 10 peaks that rise above 16,000 feet (4,900 metres), including the highest in the range, Margherita Peak (16,762 feet [5,109 metres]). There are glaciers and glacial lakes. In the late 1880s Henry Morton Stanley became the first European to reach the range.
