Iron-stained stream at Stony Heap
Iron-stained stream at Stony Heap
It's not the stream itself, the water, that's coloured - it's the rocks of the stream bed, even though the source of that colour does lie in the flow. The stained course is a tributary of Newhouse Burn which flows left to right in the foreground. The line of that stream is not coloured before the confluence but it becomes so.
A Wikipedia entry tells that the cause of the deposit is the oxidation by bacteria of dissolved ferrous oxide which results in the deposition of insoluble ferric oxide.
There are old coal mine workings in the area and the origin of the water could be from such an underground source.
