Before tears of the kingdom came out, I was watching a video on youtube that talked about volcanic signs around hyrule. As they pointed out what different structures around death mountain and akkala could've been, I started seeing those kinds of structures and shapes everywhere and I realized..
Hyrule is on top of a very large volcanic area
I started looking for signs. I realized there were hot springs in tabantha, and hot springs is not just something that cold regions have, no, it's something volcanic regions have.
When tears of the kingdom came out one of my top priotities was to get to the depths and see if there's lava underneath these hot springs, and sure enough there they were! Not only that, I found volcanic shapes in the depths themselves, as well as lava in other places I didn't know about.
Why am I talking about this?
Because they're not just there as decorations, at least not to me.
Look at Hyrule great forest. It obviously used to be a big forest spanning from above hyrule castle all the way to the top of the map, covering the west part of death mountains foot. Now the trees are all burned down from a volcanic eruption, except for in two regions that have strangely moat-looking "rivers" around them.
I'm not going to pretend I believe these are rivers. I'm 100% sure they are man made. These moats were dug in order to protect important land marks, because the people knew that they live on a volcanic region. It's no coincidence that the castle has a huge moat around it as well. They are trying to be safe from their inevitable doom.
But it's not just this. Moats don't always save you, and volcanoes eventually go dormant.
I imagine if you're the least interested in zelda lore and the zelda timeline, you've asked yourself the question, "Why does the map change so drastically?". Well, here's your answer.
Death mountain isn't just any mountain, it's always the most recently active volcano and the place where the gorons live! The gorons move around, when there's a new volcano they move there!
Towns safety become threatened, and so they move. Look at the ruins on the sides of death mountain, they're not burned, they're abandoned. So the people move around, they literally have no choice but to do so, unless they take to drastic measures, like raising your town high above the ground and building a wall around it, like the great plateau.
Why are the sheikah towers buried under ground and designed to shoot up with incredible force? Why not just build them in place and why do they need to be so tall? Maybe they were preparing them to be able to function even after lava has covered the ground.
The extremely mountainous nature of all of hyrule is honestly the best sign we have of this. By looking at the mountains we can conclude where the latest volcano was, and I think it was in Hebra.
So when trying to piece together how the maps work together, you can't look at things like a town, a castle or a volcano, because those things are constantly moving. I'd say maybe the desert could be the way to go, but we've seen very clearly that deserts used to be oceans. If you look to the horizon in gerudo desert in botw, you'll see water.
I think that the gorons migrate when their volcano gets too cold. If we look at majoras mask and assume that termina is in fact a real place, this is the first time we see gorons living in a cold place, and they don't seem to be thriving. Gorons like the warmth that the volcano provides.
So why does death mountain switch places?? Because it's not the same mountain! Death mountain is always the volcano! So one volcano goes dormant, another one pops up and the gorons move there. And this also explains a loooooot of other geographical questions. The people of hyrule are living under a constant threat of destruction by volcano, and that's why they need to move their castles and everything. If we were to assume the temple of time from ocarina of time is the same as in breath of the wild, we clearly see they moved/abandoned the castle and castle town because of the close proximity of death mountain in ocarina of time. It all makes a lot of sense and makes me feel like the map changing isn't such a big problem to me anymore.
