Mount Cameroon is one of Africa's largest volcanoes, rising to above the coast of west Cameroon. It rises from the coast through tropical rainforest to a bare summit, which is cold, windy, and occasionally dusted with snow. The massive steep-sided volcano of dominantly basaltic-to-trachybasaltic composition forms a volcanic horst constructed above a basement of Precambrian metamorphic rocks covered with Cretaceous to Quaternary sediments. More than 100 small cinder cones, often fissure-controlled parallel to the long axis of the massive volcano, occur on the flanks and surrounding lowlands. A large satellitic peak, Etinde (also known as Little Mount Cameroon), is located on the southern flank near the coast.
