limestone caverns
Subterranean rock hollows
Limestone caverns are natural underground chambers formed when slightly acidic groundwater dissolves limestone rock over thousands or millions of years.
These caverns often feature stalactites, stalagmites, and other mineral formations.
Famous examples include Mammoth Cave and Carlsbad Caverns: We toured the limestone caverns and saw ancient rock formations.
