 The town is close both to the west coast of Eyre Peninsula, and to the Gawler Ranges.It is located in the centre of a vast low-rainfall wheat belt and the surrounding countryside includes numerous wind-shaped granite outcrops.The 'wave' shapes and varied colours of the granite outcrops or bornhardts in the area were formed by moisture-induced decomposition of the sub-surface granite when the ground level was much higher.
