I guess I know what you see in this map, but I am sure you don't speak/read German, correct?
The map that you most probably identify as a cave side view that shows that there is an entry in the Arctic, is only a top view of shipable passages in the area. The map below then shows the actual depth of the route indicated above.
Helps to be able to read documents before posting shit on the Internet. But you are American therefore pic related.
