Shorty’s Terror is enough to frighten the hardiest soul. The massive cave narrows to a tube and the cave floor descend into unfathomably deep water, leaving the caver no option but to cling to the roof, walk on the walls, brace above the thrashing river. Meanwhile the pressure difference from one side of the mountain to the other creates a gale-force wind the howls through the passage, which then narrows to a ‘squeeze’. It’s sensory overload, and not in a good way.
