Series of rimstone dams, or cave gours, block the pool to the northwest
and lead up to a flowstone deposit down to the southeast.  The slow decline
has allowed sediment to deposit laminally, forming a series of stairs that
go southeast.  A fat and gnarled pillar stands in the center of the room.  
A baby bat sleepily hangs from the ceiling.
