The stair climbed through the roof of the Chamber and then ascended to the junction with the Awful Path.The twelve exposed portions of the stairway were very hard to climb.There were three traps along the steps: Trap 2: Similar to trap 1, this trap was at the 120' point and corresponded to the seventh exposed section.There were six stairs here, the even ones (2,4 &6) being trapped.The trap released with forty or more pounds of pressure, causing all six stairs to slide into the column for ten seconds.
