This map was compiled by Finlayson from existing maps of the early explorers, official surveys, and the work of Charles Chewings (see AA 59), Cecil Madigan, Michael Terry (see AA 333) and Donald Mackay. Marked on the map are the routes of Finlayson's expeditions in the area from 1931 to 1935. Additional information relating to geography, geology, exploration, fauna and flora in the area is also included on the map. The map is overlaid with a reference grid, numbered from 1-40 across the bottom of the map and marked from A-Z along the left-hand side of the map.
