cave system
Subterranean passage network
A cave system is a network of interconnected underground chambers and passages, often formed over millennia by water dissolving limestone or other soluble rock.
The term emphasizes that caves rarely exist as single rooms—they branch, connect, and extend in complex patterns: Explorers mapped over twelve miles of the cave system.
Major cave systems may have multiple entrances and distinct zones with different conditions.
