It is a 5.5 km walk to the main Art Gallery at Carnarvon Gorge, crossing the creek many times - it is pretty easy walking and well worth the effort - the art on the cliff is approx 3,500 years old and is stencilled - made by mixing ocre with animal fat and saliva and being sprayed from the mouth over the object - hand, boomerang etc. The hands in the top centre in a cross pattern are thought to represent a human compass - friendly relations between neighbouring tribes. The net represents death - this was an area for ceremonies and burials. The double boomerang is thought to be a sign of good hunting as they are the shape of killer boomerangs - they don't return and go low to the ground to kill a kangaroo or goanna etc.
