Better Caves Archaic - Complete Underground Overhaul
The mod completely transforms standard cave generation in Minecraft, adding brand new types of underground formations to explore. Players will discover underground lakes and rivers, massive lava oceans, and many other interesting locations.
The main feature of this mod is the incredible variety of cave systems. In addition to traditional tunnel-shaped caves, you'll encounter huge spherical cavities, some filled with water and others with molten lava. All these parameters can be customized to your preferences. Such diversity makes every underground adventure truly exciting.

If you encounter any issues or have suggestions for improvement, you can leave feedback on GitHub.
This is an unofficial port of YUNG's Better Caves mod for version 1.7.10 on Forge.
