A Bit of Geology

The Natural Bridge is a granite formation that looks just like a giant rock bridge! This ‘bridge’ is caused by the gradual wearing away of the granite rock by the Great Southern Ocean. 

The natural bridge formation is a reminder of the power of the ocean. It is incredible to watch the waves roll across the ocean, crashing into the granite cliffside and rushing under the bridge.

1,600,000,000 year old rock formations.
There are 2 distinctive rock types here that resemble granite, a common rock on the south coast- granodiorite and gneiss. The former is an igneous rock that is rich in silica while the latter is a metamorphic or changed rock, and pronounced as ‘nice’.
