Bourke's Luck Potholes. This formation was formed where sustained kolks (underwater vortices) in the Treur River's plunge pools have eroded a number of cylindrical potholes or giant's kettles, which can be viewed from the crags above (as here). It was named after a local prospector, Tom Bourke, who predicted the presence of gold, , though he found none himself. Photographed in Blyde River Canyon Nature Reserve, South Africa.
