Meramec Caverns, Show cave in Ozarks, Missouri, United States.
The cavern system extends 4.6 miles underground, featuring elaborate mineral formations, limestone deposits, and natural aragonite structures throughout its multiple chambers.
French miners discovered the caves in 1722, which later served as a saltpeter extraction site for gunpowder production during the American Civil War.
The cave's ballroom area has hosted square dances since 1890 and continues to serve as a concert venue for musical performances throughout the year.
Guided tours lead visitors through illuminated walkways while maintaining a steady temperature of 60 degrees Fahrenheit throughout all seasons.
The Wine Room contains a six-foot-high aragonite formation called The Wine Table, recognized as one of the most unusual cave structures worldwide.
