This 290-million-year-old volcanic remnant is a geological wonderland with rock pools and permanent water flowing into cool water holes.
The Glacial area is a great spot to explore, relax and enjoy the great outdoors and the crystal-clear water is very soothing on a hot summer day, making it an ideal location to enjoy a picnic and a swim.
Before you jump in your car and head out there – be warned, there is no ice to be seen! Nor will you find any of the typical glacial landform features, such as steep-sided, flat-bottomed, U-shaped valleys. These landform features are the result of glaciers that existed during the last one million years, in the Pleistocene Epoch.
The Rocky Creek glaciation is so old it predates the Pleistocene Epoch and can be traced back some 290 million years to the Carboniferous Period. A vast amount of weathering and erosion occurred over 200 million years, so all the original glacial landscape features have been eroded away and replaced by those typically associated with running water.
How then do we know a glacier did exist in this area? The answer lies in the creek bed. It is best to pick a spot down close to the water where flood borne gravels have ground the rock down and left a nice ‘polished’ surface to look at. You will see it is made up of many different sizes and types of stones, all cemented together in a matrix of finer gravels, sand and clay. It is a conglomerate, or to be more exact it is a fluvio-glacial conglomerate.
So how did it form? As a glacier flows it gathers and carries with it broken rock material. Eventually, all this transported material is deposited at its terminus, that is, the point at which higher temperatures cause the glacier to melt. Of course, this is the simplified version!
If you wish to continue this geology lesson, pick up a more detailed information leaflet at the Bingara Visitor Information Centre. And if geology’s not your thing, the glacial area is a spectacular location to take in scenery and enjoy the serenity.
Camping is permitted in this area although there are no facilities. Please take all rubbish with you.
