Upper Wentworth Falls in the Blue Mountains of New South Wales, Australia. The 187-metre (614 ft) three-tiered seasonal waterfall is fed by Kedumba Creek and is the namesake of the nearby town of Wentworth Falls. Near the falls, there is a rocky knoll that has a large number of grinding grooves created by rubbing stone implements on the rock to shape and sharpen them. These marks have been determined to be signs of early human habitation nearby.Photo credit: David Iliff
