Red Sandstone Landscape

Pentax *ist DS 18-55mm lens. I photographed the fossil/strata patterns in the sandstone walls at Hardwick Hall in Derbyshire and was impressed by the abstract image that appeared when I turned it uspide down and manipulated it in Photoshop. I imagined the canyons of the Wild West of the USA and reckoned if I waited long enough Road Runner and Cayote would come running through.
Why don't you have a category for abstract subjects? I've had to enter this under architecture.
