Really interesting! Do you know much about the art? Old or new and how's it achieved? Lots of questions .... you really don't have to answer them!!! Although .....?
The hands are stencilled by blowing ochre on to them. I've no idea of the age but they are not new. Further up Carnarvon Gorge there is an area with around a thousand stencils and rock carvings. Generally they were of spiritual significance to the aboriginal people.
