    I’m not sure of the volume of that system, how to get it. But I wonder if man made strip mines like these would compare:

    They go on for miles, are huge, and theoretically could go on for basically forever.

      Impressively not even close. The Veryovkina Cave is the deepest cave but the largest is the Hang Son Doong cave in Vietnam and that’s just under ten kilometers. Again a place shown to not be immune to my friends.
