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 variations, 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 datapacks.
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.


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:


Areas without trees that break the monotony within forests:


Circular mushroom patches that generate within forests:

They generate at the bottom of all deep oceans.

They can have stagnant water.


The mod is configured through datapacks that replace the integrated JSON files. Some of those are:

Note that although this mod appears to reuse Minecraft's density function system, in practice most vanilla function types (noise, cache and interpolation ones in particular) and everything that depends on them (such as overworld biome parameters) don't work on Landmarks features, and Landmarks analogues don't work outside of its feature type.
