Where are caverns located?

Caverns, or caves, are typically located in areas with soluble rock formations, such as limestone, gypsum, or salt. They often form in regions with significant geological activity, including karst landscapes, where water erosion has created underground voids. Notable locations for caverns include the United States (e.g., Mammoth Cave in Kentucky), Europe (e.g., the Postojna Cave in Slovenia), and parts of Asia, among others.
