I'm working on a new desert biome. While checking out some older maps I've made, I've noticed it's been a while since I last made a pack with some larger landmark features you see the best when you combine all sheets. So I figured out, it might be cool to make this round Caldera pack.
Maps are going to have this strong division between lower and upper levels, with higher levels being more dry than lower ones. With arranging sheets differently, it can also work as a huge mountain ridge in the middle.
