Map of southern Tharsis
by WingofCootMap of southern Tharsis, with the territories of the other four tribes; 24 miles per hex.
This map lines up directly with the northern Tharsis map - the northwest corner of this map to the southwest corner of that map. The southeastern edge also aligns with the northeastern edge of the Noctaurus map.
(I call this "southern" Tharsis, but on RL Mars the region extends further south; there's a third giant shield volcano. But this is the southern part of the territory of the Sandfolk of Tharsis, except for where the Steep Cliffs tribe overlaps into Noctaurus.)
