Fairy Chimneys

Today I head back to Istanbul but I couldn't go before sending a couple of photos of the geological feature that probably defines Cappadocia- the Fairy Chimneys. They aren't due to the volcanic nature of the region but are rock formations worn down over time, harder rock on the surface and softer underneath. 

You can tell that I'm not a geologist! The last one is slightly different and I'll leave you to guess what it might remind you of.
