The basalts in the Yarra Bend area originated from two separated volcanic lava flows. The first filled the ancestral Merri Creek Valley approximately 2.2 million years ago; the second flowed down the valley of Darebin Creek and into the Yarra Valley around 800,000 years ago. The Merri and Darebin creeks managed to reestablish their flow across the basult, however the Yarra was blocked, producing a lake and broad floodplain upsteam of Kew. Eventually the Yarra began to cut a new course between the basult and uplifted silurian mudstone/sandstone sediments which dominate the southern part of the park. The current course of the river meanders with very steep outer sides and gentle slopes on the inner sides.
The natural state of the area has been completely clean. It might seen to have a bit of litter on the sides but the creek itself is always an example of Melbourne's environment today.
