Two dragons snapped recently at Priddy Mineries in Somerset. It's the site of old lead mine workings.
The lead contamination makes the site unsuitable for agriculture although the lake where these dragons were found is used for coarse fishing. The result is a very important site for nature and one of the few acidic pools in the largely calcerous Mendip Hills.
