The distinct, light pink, coarse-grained granite boulders that frame the
picturesque Auburn River are links to an earlier time in the Earth’s history.
About 250 million years ago, molten magma was generated from pulses of heat in
the Earth’s crust. The molten rock remained at great depths and gradually cooled
beneath the Earth’s surface. Overlying sediments were gradually eroded by water
in streams. This slowly reduced the weight of rock above the granodiorite, a
type of granite, allowing the granodiorite to expand upwards and crack along
fractures. Continual weathering by water along the fractures decomposed the
granodiorite and formed the gorge of Auburn River.
The weathering action of fast-flowing water has created so called ‘dinosaur
eggs’. These large, round to egg-shaped chunks of granite (granodiorite) weigh
about one ton each. They were formed after being trapped beneath the water and
swirled by the force of the river in a confined space. Slowly but surely, the
erosion continues today, as the river continues to sculpt the surrounding
Calistemons, leptospermums and stunted figs are found along the river.
Bottle trees (Brachychiton rupestris) are quiet common. The
rainforest species occur in some area on the northern river bank. The
open eucalypt forest includes the common silver-leaved iron bark (Eucalyptus
melanophloia) and the forest red gum (Eucalyptus tereticornis).
