Generally, the middle-forward part of the stern section is 2nd class down to F-deck. G-deck and the Orlop contain ship's stores of mostly food items.

The Orlop deck represents the mud line, some 20 feet (6 meters) above the keel. The exposed outer edges are all refrigerated cargo. Large amounts of the refrigeration coils from the walls are found in the debris field. More detail

F-deck forward was 2nd class cabins and an outer section collapsed onto G-deck as a result of implosion.

D-deck aft slopes down on to E-deck, which collapsed on to F-deck, leaving a large deep indent into the starboard side. This was the result of implosion as the water poured into the upper decks before the lower decks had filled. The collapse of the decks allowed the sides to tear loose.

D&E-decks forward of the big slope were 2nd class. E-deck was second class cabins. D-deck housed the dining room and is flattened by C-deck above. More detail

C-deck in the photo was a promenade for the 2nd class. A&B-decks shifted inward, and fully exposed the C-deck promenade. Based on the relation between the windows of the 2nd class Library (lounge) on C-deck and the crane above on A-deck, this portion of C-deck fell or shifted aft by 10 feet (3 meters).

B-deck is shifted inward some 10 feet (3 meters) with A-deck. The #4 cargo hatch to the right of the letter B is WAY out of alignment with the split C-deck walls.

About 70 feet (21 meters) of the Boat Deck peeled up and now hangs over the side.
