23Natural EnvironmentGEOGRAPHICAL SITUATIONShaped like a triangle, Cameroon is built over an expanse of 1200 km on its height from the Gulf of Guinea to Lake Chad, and a base of 800 km for 475,422 km2. It is stretched out from latitude 2° to 13° north and 8° to 16° lon- gitude east. Cameroon shares borders with: the Federal Republic of Nigeria in the west, the Atlantic Ocean in the south-west, Guinea Equatorial, Gabon and Congo in the south, Central African Republic and Chad in the east, and Lake Chad in the north. At the junction of the West, Central and North African geographi- cal regions, Cameroon is the meeting point of three of the most important regions of Africa: Guinea coast, with its black tribes, western Sudan, whose people are Fulanis and Arabs, and Congo populated with Bantus.RELIEF AND VEGETATIONRELIEFCameroon is unique by virtue of its extraordi- nary contrasting relief which offers both hills and valleys. The ridge crossing obliquely the country from the south-west to the north-east (from the depth of the Gulf of Guinea to theextreme-east of Adamawa) is the most noteworthy element of this whole.This could be divided into two distinct regions: the Adamawa plateau and West high lands.Adamawa plateau is an enormous lifted and faulty shelf of 1 100m average height on which you find dominant flat surface areas.Great basalt lava flows had poured out on this horst and were followed with trachitic and trachy- phonolic protrusions. It is nearly 400m higher than the Benoue plain through the cliff of Ngaoundere and it goes down sloping slightly toward the south.As for west high lands, they are made up of a group of plateaus mingled with deep valleys on which you often meet volcanic mountainous mas- sifs. These volcanic massifs are the highest moun- tain tops in the region, among them we have: The Mount Cameroon or “chariots of gods” 4 095m, Mount Oku 3 008m, the Mount Manengouba 2 490m, the Bamboutos Mountains 2 740m.In the north of Cameroon ridge, you find low lands composed of two units: the isolated plains and massifs. Chad plains slope gently downLES ATOUTS ECONOMIQUES DU CAMEROUN
