You should be aware that Darfar (as in Darfar Bridge, Pot, etc.) is misspelt as Dafar on OS maps of a certain scale. On larger scaled (more detailed) maps it is correct as you can see on the excellent Magic web site. This map shows the correct spelling and this one the incorrect spelling. (Then of course there's Darfur, which is a place in Africa...)
On one occasion in 2007, the manhole covers over Riverside Swallet and
Moonmilk Pot were removed and then just 'placed' back over the entrances
so that any member of the public could open the entrances and fill them
with rubbish. Can anyone visiting any of the caves with manhole
covers over them, please refit them properly.
A pair of molegrips can be used to 'adjust' the edges of the covers if
they don't fit back on properly. (They should do if they were removed
properly and then replaced the same way round as they were fitted
originally.)
It's a bit of a pain, I know, but if they get filled in again then D.P.C.
members may not be around to re-empty them. We have already done it once in recent years!
