Just a few minutes after I re-stacked the rock cairn to what is shown in the photo above, some hikers came past, and one hiker decided to try to add one rock to the top of the cairn. His action caused the cairn to collapse, much to his embarrassment and our amusement. He quickly tried to re-stack the cairn before walking off.
This is at Sullivan Rock in Jarrahdale, where we stopped after a sunrise photoshoot elsewhere in Jarrahdale (photos still to come) on Easter Monday. It is a huge rock in the bush, and is very accessible, as it's located right near Albany Highway (and is somewhat similar to Boulder Rock in Karragullen).
There were numerous rock cairns like this located at various places on Sullivan Rock. I don't know if they were marking any specific spots, or if they were randomly placed by previous visitors. Post a comment if you know.
