It was full day.
Cutting up through the towering granite scarps was a rift.

In it the black shadows clustered thickly.

Straight toward that cleft we sped.
As we drew near, the crest of the Shape began swiftly to lower.

Down we sank and down--a hundred feet, two hundred; now we were two score yards above the tree tops.
Out shot a neck, a tremendous serpent body.

Crested it was with pyramids; crested with them, too, was its immense head.
