There are thousands of red, white, purple and vemilion colored
rocks, of all sizes, resembling sentinels on the walls of castles,
monks and priests in their robes, attendants, cathedrals and

and steeples, niches and recesses, presenting the wildest and most
wonderful scene that the eye of man ever beheld ...
