Personally, I have never liked 'Silbaby', but haven't been able to come up with an alternative.
Whether we like it or not, the nick-name 'Silbaby' for the mound against The Great Bank has been adopted by people round here and so should feature as an alternative title.
I have no strong objections to 'The Great Bank', though it doesn't sound thrillingly megalithic or make specific reference to it's unnatural, mound-like qualities...
How about 'The Great Bank Mound' or 'The Mound of The Great Bank'?
I dunno!
