It all began 1700 million years ago…
Cobbold Gorge was created by a series of geological processes. Sand and mud sediment was deposited on what was then the ocean floor until eventually layers built up to be more than 10 kilometres thick.
Movement in the Earth’s crust caused the sediments to compress, forming the Hampstead Sandstone. Further movement caused the 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. Minor movement in recent times (thousands of years ago rather than millions!) have contributed to the formation of the lower reaches of Cobbold Gorge as it is today. The unique narrow gorge is set amid rugged sandstone formations occupying an area of about 80 square kilometres with spectacular, 30 metre cliffs that narrow to just two metres wide.
Evidence of the geological processes are clearly visible. An expert guided tour and boat cruise or scenic helicopter flight provides visitors with an unforgettable insight to an ancient geological story which continues to unfold each day.
In order to protect the fragile environment, access to Cobbold Gorge is by guided tour only.
The south-western extremity of Robin Hood Station, the mouth of Cobbold Creek — with its permanent, clean water — was always a popular watering hole for cattle. The Clark and Terry families both visited the spot over the years but its isolated location on the edge of a 330,000 acre property meant that it was mostly left undisturbed.
