Tree scarring was once widely practiced by Aboriginal Australians as a way to indicate their sacred sites. They would strip pieces of bark off the surrounding trees, using the pieces to make coolamons and even canoes, and overtime the trees would heal themselves, growing new tissue called "overgrowth" to seal the cuts. However the bark would not grow back, leaving oval-shaped markers that are still clearly visible hundreds of years later.
There is also a sheltered picnic table, public BBQ and water tap.
