The Geology of Self-Replenishing Caves
This cave system represents a rare geological balance where erosion rates match excavation speed. The phenomenon occurs in specific karst or volcanic formations where overlying material constantly weathers into transportable fragments that fill void spaces below.

• Angle of Repose: The debris maintains a consistent 35-40 degree slope—the natural angle at which loose material stabilizes until disturbed
• Hydrological Action: Water percolating through upper layers gradually loosens new material at rates of 5-10 kg per hour, ensuring continuous supply
• Void Migration: As lower debris gets removed, upper cavities collapse and redistribute material downward through interconnected fissures
• Engineering Implications: Conventional excavation becomes ineffective, requiring specialized techniques like simultaneous support installation during removal

In this natural conveyor belt of stone and soil, we witness geology's persistence—where the earth actively resists human intervention, reminding us that some natural systems maintain their balance despite our best efforts to rearrange them.
