So I have been working on a (very very VERY rough) map of the Pridelands for future reference in writing and I think I have the very general form of it from at least the first (and nominally third) movies?
It's incredibly rough but I might make a better version of it later, mainly I wanted to get the locations correct.
We know that Pride Rock faces directly east from the scene where Mufasa and Simba watch the sunrise. From this scene we also know that the watering hole is directly to the east of PR and that a river flows from the east before curving south (it zigzags more in universe, again simplicity). We also know that the Elephant Graveyard would then be to the southeast, probably bordered by mountains (which I will add later.
The gorge is, I think, to the west of PR, since when Simba goes into exiles he walks into the setting sun AKA the west, and if he was leaving the Pridelands it would make sense that the Gorge seems to denote their west border? SP also indicates this but I did not inculde SP locations yet. We also know that there is a river (maybe) that flows through the gorge, and that it leads into the Oasis. For the position of the Oasis, I think it has to be in the northwest since when Simba goes to it he apparently is approaching it westward, but when he comes back to the Pridelands he comes from the north (since PR is facing the left).
We also see in the return scene a dried up river that flows from the north down and probably around PR, since we didn't see it in at the beginning. Also ignore the fact that everything is made of ovals, I will go make up shapes for the actual lands later. The outlands would probably be in the southwest corner on the other side of the Gorge, especially since I headcanon that Simba had the dam from SP built in order to reinvigorate the Pridelands, but that might cause geographic changes? Or maybe the gorge floods in heavy rains.
