You are nearing the end of this long huge gallery.  The forest of
redstone columns continues on all the way to the end.  The smooth floor
seems to have retained a little of its original texture here since this
section of the hallway was not frequented as often as the rest.  The texture
of the floor is very rough and covered with gravel, which makes a strong
crunching sound as you walk along the hall.
