Cave Digging is the practice of enlarging undiscovered cave openings to allow entry. Cave digging usually follows a search of mountains and valleys in karst topography for new caves. Often it takes place underground in places where a large passage has clearly been backfilled with silt, or choked with boulders. Sometimes chisels or explosives can be used to widen constrictions in the passage when spaces are evident on the other side.
Digs are in unstable parts of a cave and often need to be shored up with scaffolding or concrete to prevent re-collapse. It can be a dangerous activity, depending on the circumstances.
