The “Two Camels” of Koussa: A Massive Ferrous Meteorite in Mayo Binka (North-West Region in Cameroon)


At Koussa in Mayo Binka, a hundred kilometers northeasterly from the town of Bamenda, the Capital of the North-West Region in Cameroon, an enormous block of native iron of several tons in mass is found. The observation of the Southern view of this block let anyone see a configuration which surprisingly recalls two camels in an attitude that these animals generally adopt when they are at rest. This strong resemblance with the attitude of these animals in rest has led the local populations in identifying this enormous metallic block with the name of “the two camels’ couple” or simply stills “the two camels”. The test conducted with the acid let the Neumann figures be revealed the Neumann figures which confirm this metallic block as being a ferrous meteorite or a siderite of the Hexaedrites class.
