Landmarks

Landmarks is a worldgen mod that adds some natural features to the Overworld.
Other than aesthetics, the purpose of this mod is to make each area more distinctive through small-scale details that complement the existing large-scale terrain and biomes varations, and make it easier to recognize a certain place from looking around rather than using coordinates, hence the name. For this reason, the features are all procedurally generated and are neither ubiquitous nor rare.

This mod is server-side.

You can now add, modify and remove palettes with a datapack.

Rock Formations

Rock formations are highly diverse features that generate in every overworld biome (with some biome-specific variants). They can be made of different materials and can be small, big, isolated, clustered, smooth, rugged, etc.

Ponds

The loathed ponds are back from the grave. But they’re not as frequent as in <1.17, and the partially buried kind is even rarer. They're also a lot more varied in appearance:

Forest Clearings

Areas without trees that break the monotony within forests:

Fairy Rings

Circular mushroom patches that generate within forests:

Thermal vents

Sinkholes

More will be added…
