Just looking at this geology map - this is the 1895 Rothbury Drift sheet 1:63,360, 1 inch to the mile. Amble is in the top right corner. Shows a zone of 'old pits' where the new estate is, as mentioned above. Also a bunch of 'old pits' at the bottom end of Amble -Ivy Street, Leslie Drive, Lawrence Ave area??

I'm delighted the Geological Survey are putting this stuff online.
