A new Greenwich blog site - http://subterraneangreeenwich.blogspot.com/2010/01/greenwich-sand-mine.html covers all things underground in Greenwich. But, perhaps its me doesn't understand - but I can't see anywhere to leave comments on the blog. Their latest post is, interestingly, about the west Greenwich sand mine.
Now- I was going to point out that Greenwich Industrial History Society covered this in the very first edition of our newsletter back in 1998 - I could reproduce the article - following a survey done by Nick Catford for Kent Underground Research and Sub.Brit. We even had a speaker on it.
Would be nice to liaise ........................ and would be nice to invite them to come and speak to us,
