I was reading "Cozumel Dive Guide and Log Book" and they made a reference to the Cathedral and the Little Cathedral. I did a Cathedral dive in May where we exited a cave which ran through a wall at a depth of 113 ft. The wall was almost vertical and there seemed to be a virtual abyss below. I didn't notice a cross; I'm not sure I even looked at the ceiling. Was this the Cathedral or the Little Cathedral?
