Photographer’s Note

Walking to Squeaky beach from Tidal River in the Wilsons Promontory National Park you come across this well-developed tafoni (weathering cavern). Tafoni are found chiefly in igneous rocks (although they can occur in sedimentary and some volcanic rocks too). There is some debate about how tafoni form, but most theories revolve around water entering the rock mass, evaporating and hardening the upper surface while leaving the lower surfaces more prone to weathering (thanks to Cooperative Research Centre for Landscape Environments and Mineral Exploration)
