Blue Spring Cave, Underground cave system in White County, Tennessee, US
Blue Spring Cave is an underground cave system in Tennessee featuring extensive limestone passages and flowing water systems. The cave stretches through multiple chambers connected by large corridors that wind through the rock formations.
The cave system expanded in exploration during 1989 when cavers enlarged an opening, uncovering the Johnson Avenue passage. This breakthrough led to ongoing mapping efforts that revealed more of the system's extent.
Scientists and researchers regularly study the cave's ecological systems, focusing on bat populations and the underground water network's impact on local geology.
Access to the cave requires advance permission from the property owners and entry through a secured gate. Visits cannot be done on impulse and must be arranged beforehand.
The cave preserves footprints from Ice Age jaguars discovered deep within its passages during exploration. These tracks suggest ancient openings to the surface that have since collapsed.
