Shoreline, dykes, aboiteaux and placement of dyke walls and aboiteaux

Three base maps of the dykes, aboiteaux and shoreline from Wolfville to Grand Pre from 1760 - 1973 altered by Sherman Bleakney. Bleakney has indicated, in colour, the system of dyke walls from 1760-1950. Probably compiled by Sherman between 1994 and 1997.
