40 Strange Cave Discoveries That Are Hard To Be Explained
Vogelshacht And The Lamprechtsofen

These are two really deep and huge caves. Now the story that leads them to this list of extraordinary cave explorations is that at a point they were connected. One opened to the other. Now that makes this set of caves potentially one of the deepest caves to be ever explored. And for the record, we’ve yet not reached its deepest point.
These caves are located in the Leoganger Steinberger area, in Salzburg, Austria and extend down to at least 5,354 feet deep. To explore deeper into them, scientists might need to use explosives but this option is yet being explored.
