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 | |
