Hi all,
Has anyone got or can point me towards a map that has the DYO and OFD passages superimposed on it to show the extent of them and where in relation to surface features they lie?
I don't need anything super accurate, I just want to be able to show where they are for a talk I'm giving on South Wales caves.
Many thanks.
