The mountains formed about three million years ago in the late Pliocene epoch and are the result of an uplifted block of crystalline rocks including gneiss, amphibolite, granite and quartzite.

This uplift divided the paleolake Obweruka and created three of the present-day African Great Lakes: Lake Albert, Lake Edward, and Lake George.

The range is about 120 kilometres (75 mi) long and 65 kilometres (40 mi) wide.
It consists of six massifs separated by deep gorges: Mount Stanley (5,109 metres (16,762 ft)), Mount Speke (4,890 metres (16,040 ft)), Mount Baker (4,843 metres (15,889 ft)), Mount Emin (4,798 metres (15,741 ft)), Mount Gessi (4,715 metres (15,469 ft)) and Mount Luigi di Savoia (4,627 metres (15,180 ft)).
Mount Stanley has several subsidiary summits, with Margherita Peak being the highest point.
