A surprise well!

I was out today strolling with Mr M with my eyes peeled for any possible wells(!) and, of course, dereliction.   The latter is relatively easy, if you pick the right area, the former is rather tricky even with a map.  A lot of the wells have no significance now and just disappear.  This one at Low Austby, near Ilkley, was covered over with a very large stone flag, serendipitiously broken to allow a glimpse inside!
