About England & Wales Sections
These hand-coloured engraved ‘horizontal’ sections at six inch to one mile scale were published in the mid 19th century by the Geological Survey of England and Wales. The detailed profiles generally follow the geological dip on the one inch Old Series maps numbered in the upper right hand margin and the profile locations are shown on these maps which themselves did not include a section.
