The crest, which is very grand and beautiful, resembles in the arrangement of its rock masses, the form of a woman’s body, stretched at length upon its back, and covered by a white winding sheet. From this, the name of white woman,--_izta_, white; _cihuatl_, woman--with which this lovely mountain was baptized by the dreamy imagination of the Aztecs. THE CAVERN OF CACAHUAMILPA. In the limestone mountains of Cacahuamilpa, thirty kilometres north from Tasco, in a ravine, lies the village of the same name, near which is situated the famous cavern, one of the most beautiful in the world, commonly designated by the name of the _gruta de Cacahuamilpa_ (grotto of Cacahuamilpa).... Dominating the eminence formed in the cordillera running eastward and which has already been mentioned, is perceived the great mouth of the cavern, with the green festoons of foliage which adorn it and some stalactitic formations which seem to announce the marvels of the interior. Access to this entrance is gained by a short and narrow path. The mouth measures five metres in its greatest height and thirty-six metres from side to side; after it has been traversed, there begins a plane sloping toward the interior; the soil is sandy; shortly one arrives at the first gallery, which is lighted by the sunlight. This gallery is very large; its walls are formed of enormous masses of tilted rocks, which look as if about to fall; the spacious and lofty vault is furrowed by broad and deep crevices and from it hang many stalactites in the form of columns, or colossal pear-shaped masses of marble. Crossing the broad space of this gallery, a second is reached, where the darkness is dense and appalling, the torches scarcely dispel the gloom, and the spirit is oppressed. In the first gallery the most notable concretions are “the enchanted goat” and “the columns.” The former has lost much of its resemblance, as the head of the goat has fallen, but the second is wonderfully beautiful, because of its astonishing originality; its form is that of a column adorned with a capital, in the form of a tuft of plumes, which supports the base of a natural arch. The third gallery, called “the pulpit” on account of the shape of its principal concretion is no less beautiful, grand, and imposing, than the preceding. Here the darkness is absolute. Beyond this third gallery there are twelve more, very imperfectly known; they are called--the cauliflower, the shell, the candelabrum, the gothic tower, the palm tree, the pineapple, the labyrinth, the fountain, and the organ-pipes. The rest have no special names. All of these galleries are marvelously beautiful; all are extensive and have lofty vaultings.
