Detail of the eastern end of the north side of the passageway.
The border in this image is of different thicknesses on the two blocks. This is a scheme followed on all four corners of the passageway and is one of the few places where the decoration changes at the edge of a block. The row of blocks represented by the upper block here appear to have been conceived essentially as a support for the relief above and so were given some different definition than the blocks beneath them.
