Another shot from our Rio Tinto tour. One of the aims of the shots I was taking was to explore the combined effect of frozen surface movement with the structures that lay beneath the water's surface. This image has received only minimal processing and no filter has been employed, the colours being due to the dissolved metal salts and the microorganisms that grow on the river bed.
Here I have uploaded a 1440 pixel image ... If the larger version is too large a 1200 pixel version can be found
