The caption for my image is:
Dolerite is an igneous rock that is unusually widespread in Tasmania and so significantly shapes the landscape. It has been described as ‘the rock that makes Tasmania’. During the breakup of Gondwana, dolerite magma intruded into the crust as subsurface d***s and sills (sheets). As the magma cooled and crystallised, regular vertical cracks propagated through the sills, forming polygonal columns. The characteristic form of many dolerite cliff-lines is due to this. Less common is such a clear exposure of a cross-section of these columns seen here, forming a glaciated pavement on the Ben Lomond plateau, their outline highlighted by a light fall of snow.
