Dude you hit the 200' ice wall. It tends to sink ships never to be found and the exploration becomes a mystery.
Please provide a list of ships presumed to have "hit the 200' ice wall". If it "tends to sink ships" there should be multiple ships lost at sea due to this.
Ooh! Yes please!
And the reports of people who managed to get into lifeboats just before they hit and survived - and of airplanes and helicopters that also crashed and couldn't explore past the ice wall because...um...well, I suppose they *might* have been flying under 200 feet?
OK - forget ships...what about airplanes?

Oh! Thanks for the list! It shows the locations of all of those plane crashes...weird that NONE OF THEM are things crashing into ice walls. Removing the shipwrecks, fires and snowmobile accidents - plus the one that's "Most likely a legend" and the one that was 1400 km away from antarctica. But a bunch of those were at islands off the coast - so they didn't hit any ice-wall. So now we're down to:
1956 - McMurdo Station, Antarctica
1958 - Cape Hallett Bay, Antarctica
1958 - Marguerite Bay, Antarctica
1959 - Marble Point, Antarctica
1961 - Wilkes Station, Antarctica
1966 - Ross Ice Shelf, Antarctica
1969 - Taylor Valley, Antarctica
1986 - Philippi Glacier, Antarctica
1989 - Mirny Station, Antarctica
1994 - near the Rothera Research Station, Antarctica
1999 - near the Dumont d'Urville Station, Terre Adélie, Antarctica
2008 - near Neumayer-Station III, Antarctica
2010 - near the Dumont d'Urville Station, Terre Adélie, Antarctica
2013 - Mount Elizabeth, Antarctica
These all seem to be either off the coast or WAY inland...places where "unipolar map" FE'ers claim don't exist - and which "bipolar map" FE'ers put a thousand miles away from the ice wall.
I'm not seeing any ice-wall crashes here.
