Dummer SF51-04 — AUSTopo 1:250,000 Topographic Map (2025)

Desert ranges, ephemeral lakes, and a remote Canning Stock Route connection—mapped with authority across Western Australia’s Great Sandy Desert

Covering Dummer and the surrounding Great Sandy Desert country of northern Western Australia, this AUSTopo 1:250,000 sheet provides a clear, authoritative regional view of an exceptionally remote landscape. Long sandplains and dune systems are broken by isolated ranges, peaks, rock formations, springs, and broad ephemeral lake beds—terrain where dependable big-area context is essential.

The sheet includes Dummer Range, Newbery Peaks, Mount Rosamund, Gwenneth Lakes, Prescott Lakes, Footprint Flat, Stoneaxe Cave, and Tina Spring. It also captures a small but important section of the Canning Stock Route near Gravity Lakes in the south-western corner, making it a valuable reference for experienced expedition travellers, historians, researchers, land managers, and emergency coordinators.

At 1:250,000 scale (1 cm = 2.5 km), this is the largest scale at which published topographic maps cover the entire Australian continent—ideal for regional planning, land management, emergency coordination, and serious outback navigation.
