Wave Rock, Hayden, Australia

Wave Rock has cultural significance to Aborigines. More than 140,000 tourists visit wave rock every year.
One aspect of Wave Rock rarely shown on photographs is the retaining wall about halfway up the rock. This follows the contours and allows rainwater to be collected in a storage dam. It was constructed in 1951 by the Public Works Department, and such walls are common on many similar rocks in the Wheatbelt.
