Cobwebs cling to the corners and rubble covers the ground of this

decaying underground passageway. The stone of the floor and walls is

rapidly breaking down, and in sections has completely caved in to form

mounds of rocky debris. Quartz-like crystals imbedded in the walls

glimmer when light strikes them, sending out bright reflective

flashes. In the centre of the tunnel here, the ceiling has collapsed,

allowing passage up to a higher level.
