Considered geologically, the Island of Goree is a group of basaltic columns still standing, but a part of which seem to have experienced the action of the same cause of destruction and overthrow, as the the game 1996 of the same formation of Cape Verd, because they are inclined and overthrown in the same direction. This promontory, which forms the most western part of Africa, is placed, as it were, at the foot of a long hill, which represents the ancient shore of the continent. They have received the name of Mamelles. From this place, to the western the game 1996 of the Peninsula, the country rises towards the north-east, and terminates the game 1996 a sandy beach on the opposite side. Almost the whole north-side is composed of steep rocks, covered with large masses of oxyd of iron, or with regular columns of basalt which, for the most part, still preserve their vertical position.
