Cameroon (Group A) - Mount Cameroon Rising through the mist is Mount Cameroon, one of the ‘Cameroon line’ of volcanoes, which includes both volcanic islands such as Principe, Sao Tome and Bioko (from which this photograph was taken) and bona-fide land-based volcanoes such as Mount Cameroon. This volcanic line is unusual because it features volcanoes both on continental crust (such as Mount Cameroon) and oceanic crust (such as the volcanic islands mentioned above). The cause for the volcanism, and the so-called ‘Cameroon line’ are disputed. Some invoke a mantle plume, similar to the Hawaiian island chain. A mantle plume would have stretched the old country rock (African Shield, thought to be around three billion years old) inducing volcanism, creating the islands and volcanoes seen. Cameroon burst onto the footballing stage in the 1990, with 38 year old Roger Milla scoring four goals as Cameroon stormed to the quarter finals, the furthest an African team has ever made it in a World Cup. Their defensive frailties were exposed however as, after going 2-1 up, they lost against England 3-2 after extra time, conceding two penalties. This year their hopes lie with another ‘old man’ Samuel Eto’o, leading the line. Will they be able to stretch a little more out of him and progress further than the heroes of 1990?
