South of Georgetown, Queensland.
Occupying an area of about 80 square kilometres, Cobbold Gorge was created by a series of geological processes that began 1700 million years ago.
Over millions of years sand and mud sediments were deposited on what was then the ocean floor. Eventually the sediments built up to more than 10km thick. Movement in the Earth’s crust caused the sediments to compress, forming the Hampstead Sandstone. Further movement caused this sedimentary rock to fracture. Torrential wet seasons over many years spilled torrents of water through the narrow fractures, creating deep gorges and permanent springs and seepages.
