This natural water feature marks the beginning of the Blyde River Canyon. The potholes were named after Tom Bourke, a gold-digger who staked a claim in the Area. The two Rivers that come together to create these formations are the Treur River (river of mourning) and the Blyde River (river of joy). These Rivers got their names from an incident involving the Voortrekker leader Hendrik Potgieter.

The Sabie River is a River in South Africa and part of the Komati River System. The catchment area of the Sabie, Sand system is 6320 km2. It is one of the most biologically diverse rivers in South Africa, with generally good water quality.
It rises in the Drakensberg, flowing eastwards through Mpumalanga into the lowveld. It crosses the Kruger National Park and flows on to Mozambique where it flows into the large Corumana Dam, about 40 km from Moambe, before it finally joins the Komati. Settlements on its banks include Sabie, Skukuza and Lower Sabie.
