In Niagara Cave you will have the opportunity to see natural canyon-like passageways sculpted by water from an underground stream.

GEOLOGY

 

Southeastern Minnesota is known for its karst topogrography. Karst landscapes are dominated by limestone rock formations very near the surface. Common features of karst regions are sinkholes, springs, disappearing streams, bluffs, and cave systems. 

The cave system itself began forming millions of years ago, as water found its way into cracks and crevices in the limestone and slowly widened them, creating passageways that now give us a look into the geology below our feet in this Driftless Region.
