Balancing Rocks are geological formations all over Zimbabwe. The rocks are perfectly balanced without other supports. They are created when ancient granite intrusions are exposed to weathering, as softer rocks surrounding them erode away. They are often remarked on and have been depicted on both the banknotes of Zimbabwe and the Rhodesian dollar banknotes. The ones found on the current notes of Zimbabwe, named the Banknote Rocks, are located in Epworth, approximately  south east of Harare. There are many different formations of the rocks, incorporating single and paired columns of 3 or more rocks. These formations are a feature of south and east tropical Africa from northern South Africa northwards to Sudan. The most notable formations in Zimbabwe are located in the Matobo National Park in Matabeleland.
