A snapshot of the new caves
You can see a variety of terrain in this screenshot, including the type of variety the new noise caves can generate + lava rivers. Note that rivers are meant to be long and sometimes difficult to explore.

A small river I found deep beneath the ground.
A lava waterfall generated by the new lava rivers
Some bugs are deliberately left in to increase the interest level of caves. They can lead to a number of waterfalls throughout the world, such as this one.
Oh! What's down there?
It's always nice when the carvers align to produce very complex terrain.

A long cave with the new terrain
A long room with a lot of texture.
