Is there a new landscape that can be used for post-apocalypse?

The above video goes over different post-apocalyptic landscapes in video games. It made me ask the following question. Is there a new landscape that can be used for post-apocalypse?

Ideas

1. Swamp - this doesn’t make that much sense because there isn’t enough water to cover the highest mountains. Because of this, you would obviously have high lands and lowlands. People would not “rough” it out in the swamps when they could just migrate to the highlands to survive. To pull this landscape off your disaster would have to either get rid of mountains or introduce a lot more water. Maybe like a huge water asteroid or something.

2. Canyons - This landscape is pretty rare in real life, only occurring in specific circumstances. People don’t typically live in canyons. This disaster would have to explain why this is the only inhabitable landscape, or at the minimum why the book takes place there. Maybe there are other landscapes but they are too dangerous for the characters to exist there.

3. Biblical weather - perhaps the landscape is normal but the weather is not. For example, in Exodus, there was a cloud by day (funnel-shaped cloud) and fire by night (fire tornado). This could be added to any landscape to make it more dangerous. However, the disaster would have to explain how the weather was altered.

   • Tornados

     • snow funnels

     • fire funnels

   • Rain

     • acid rain

     • meteorites

     • Hail

4. Insect Debris - A movie did this very well, Love and Monsters. The world was basically the same. It had different landscapes, but the mutated monster and bugs left evidence of their existence everywhere. Spiderwebs, shells of old cacoons, and various insect nests, this kind of debris littered the landscape.
