About a month ago we went for a walk along the beach at Lower Largo in Fife. Old railway sleepers held together by well-rusted iron struts form a barrier to help shore up the … err.. shore.

There is the semblance of a face on the second sleeper from right here.

The texture of the rusted supports was interesting.

In this one the iron has almost reverted back to ore. It looks very like samples of haematite I have seen.
