This is an image of a quarry where they used to mine for lime. Nowadays it’s a protected nature area where nature is free to roam. It already is succesful; since a few years a pair of Eagle Owls is breeding there. In the past when i was younger, i would go here at times to dig for fossils and pyrite (fools gold). So it was nice to visit it at the view day. This is an image of a part of a long side of the quarry. You can see the layers very clearly. In the front there is a bit of grass, beyond that is 30 meters down! Always wonderful to see how much influence perspective has on an image!
