This is a dry stone wall on the edge of the North Yorkshire Moors National Park. I was first attracted to it by the many interesting shapes of rock that went into building quite a uniform structure. However, once I got the image on my computer and I looked at it more closely I became aware of the huge variety of hues and shades that made up what I thought was just a grey stone wall.
I've tweaked the colours slightly to make the contrast more obvious but not by much. I'm not sure what type of stone this is (any help gratefully received) but it is used a lot in the area for functional structures. The houses tend to be made of a much lighter and yellower stone that doesn't appear to be the soft sandstone I've seen in the South.
This image (and a number of others) is available as a set of postcards from Zazzle.
