The Cache;
Its a small systemic plastic container, not painted, with some swaps and log book inside. You might have to do a bit of climbing around the rocks in the area but its worth it just to see how beautiful the area is. Its not overly hard to find or get there but be carefull climbing around because some areas are slippery so wear good shoes. The GPS gets a little bit wavey in the area due to the high (and large amount) of rocks nearby.
Description; (from Narrabri tourism web site);
The Rocky Creek Glacial Area is yet another geological wonder to explore.
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 which existed during the last one million years, in Pleistocene Epoch.
The Rocky Creek glaciation is very much older, dating back some 290 million years to the Carboniferous Period. A vast amount of weathering and erosion occurs in 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 it 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 Visitor Information Centre in Narrabri or Bingara. And if geology’s not your thing the glacial area is also a lovely picnic spot and a great place to go for a swim.
Camping is permitted in this area although there are no facilities. Please take all rubbish with you.
Getting there
Head north out of town along the Newell Highway towards Moree.
Just 3km out of town, turn right onto the picturesque Killarney Gap Road (Bingara Road) for a further 67km until you reach the Glacial Area on your left.
