Natural system processes
evolution + development
Processes that gave rise to the site
river rejuvenation
features:
entrenched meander, former floodplain, high round hill, inner gorge, natural bridge
caused by uplift of land surfaces or sea level rise or fall

early pliocene to holocene epochs = when volcanic activity that formed the newer volcanics group took place. (csiro)
landscape is dominated by basalt, an extrusive igneous rock with small grain size due to it's rapid cooling. This is due to it being situated in the VVP.

formation of the Maribyrnong river
headwaters in macedon ranges, where vertical erosion occurs cutting down until it eventually reaches the lower course of the river, where BP is situated where the floodplain widens and alluvial meanders.
