It is, in fact, the most significant geographic feature of Guyana. Not too far from the Atlantic coast, at the confluence of the Essequibo, Mazaruni, and Cuyuni rivers is the Bartica, one of the few significant towns in this poor, strongly rural nation. Webster's Geographic Dictionary says that it was the point of departure to the local gold and diamond fields, which I suspect explains why it has a shanty about it. - RBW
