I think it is worth mentioning that if I saw a ladder going somewhere when I was looking for a 'lost' mine then either, someone found it and built a ladder, cleaned it out and left the ladder, or well that's about it. If I 'hid' a mine I certainly wouldn't leave a ladder hanging down from it. If I saw a ladder I would be reasonably certain that what ever was up that ladder had been scouted many times, the blue straps, the climbing ropes etc... The area the cross was in was not part of the bat cave, just watch you can see it isn't even a cave its a mine, sharp edges, obvious drifts, no bats, no guano. I am looking forward to the next season, if you watch you can see many things they don't say, this series will help others in their quest if they actually watch what they are seeing.
