Landforms and their related patterns of vegetation were simultaneously employed in a method for deducing inland-shore terrain conditions from aerial andor ground photographs. This method applies to inland shores of the Chesapeake Bay, drowned rivers, and other embayments it also applies, with adaptations, to the Baltic Sea, North Sea, and fjords in Scotland and Norway. Keys for the identification of landforms and their related zones of vegetation are included with tables for deducing terrain conditions from the identifications. Diagrams, oblique photographs, and plates of ground and aerial photographs illustrate the recognition of vegetation zones on landforms. The effects of soil chemistry and of soil from weathered serpentine upon vegetation are discussed and illustrated. Aerial photographs taken when snow was present on the shores of the Chesapeake Bay did not prevent satisfactory interpretation of the terrain conditions. Mine laying, barbed-wire setting, or any military movement in a cattail marsh were easily recognized on vertical photographs.
