subterranean rivers
Cavern-flowing hidden streams
Subterranean rivers are streams that flow underground, typically through caves, caverns, or porous rock formations like limestone.
Some rivers disappear into the earth and reemerge miles away; others flow entirely beneath the surface.
The term also applies figuratively to hidden currents of influence or emotion: Subterranean rivers of resentment ran through the organization.
