Cuyuni-Mazaruni has Venezuela as it’s border to the east and the mighty Essequibo River flows on its western side. To get to this region one needs to journey deep into the county of Essequibo. This region consists of areas such as the Upper Mazaruni, the Kartabo Village in Lower Mazaruni and the Bartica Triangle. The Upper Mazaruni River basin is a region of steep slopes which flatten out at the top to form plateaus at the western end. In Kartabo the population consists of many Amerindians as well as some coastlanders who engage in gold and diamond mining.
