Site description: Disused limestone quarry.

Conservation: Owner is particularly interested in the wildlife attracted to the site, therefore it is important not to disturb the site unduly.

The present exposure is somewhat overgrown at the western end, but better at the eastern end. In addition there is an exposure in the river bank below the quarry.
