One unique and different formation is known as the Queen's Draperies, which are found at the southwest side of the room. They are a form of massed stalactites grown together so evenly that they resemble a huge drape from which the wrinkles haven't been ironed out. But the unusual feature is the ability of this stone to absorb light and reflect it moments after the light has been extinguished. These portieres are the highest in the Caverns, being slightly over 40 feet. Throughout the rest of the room one feels as though he must have interrupted Mother Nature while she was busily experimenting and trying to decide what to do next, having left behind her first efforts for the world to see. [Illustration: © BY ROBERT NYMEYER The Chapel or Dome Room in the Big Room] The paved trail continues through a low, rocky passageway at the far end of the Queen's Chamber and presently the party finds itself in the Papoose Room and in one of the lowest spots in the Caverns, approximately 875 feet below the surface. Here the stalactites have grown together in such a way as to resemble huge curtains of stone which appear much like a sheet of lava which has slipped through a crevice and then hardened. Here, too, are numerous needle-like points protruding down from the ceiling as though sharp pointed pins had been pushed through from above. Areas on the floor remind the visitor of a growing rock garden, yet there is not a green leaf anywhere to be seen. Nevertheless, few gardens offer any more beauty or color than these gentle formations along the edges of the Papoose Room, smallest of the scenic chambers on the trail. Here the party must retrace a few steps, returning through the King's Palace, leaving this time by the eastern end, entering a small passageway which leads to a series of sharp turns and switchbacks made necessary in order to climb the rather steep grade ahead. It has now been an hour and 45 minutes since the visitor left the outer world behind, and the up and down climbing has done its part towards working up an appetite. But if that hasn't been enough, going up this zig-zagging hill should complete the task and make anyone ready for something to eat. Appropriately enough, it has been tagged Appetite Hill, and uses 60 feet to accomplish its task. A moment later the party passes by a room of rocks which looks as though it was noon hour at a rock quarry, and the workmen had scurried off at the abrupt blow of the whistle, not caring in what manner of disarray they left their chores. But in this case it was Nature's workmen who left--untold hundreds of years ago--never to return. Labeled the Bone Yard, it features an alcove where the formation resembles a huge sponge--rock eaten away or dissolved by the continuous action of water which, at times, resembles bone formations.
