疯狂山脉（VIII）(5)

This vast nighted gulf had undoubtedly been worn by the great river which flowed down from the nameless and horrible westward mountains, and which had formerly turned at the base of the Old Ones’ range and flowed beside that chain into the Indian Ocean between Budd and Totten Lands on Wilkes’s coast-line. Little by little it had eaten away the limestone hill base at its turning, till at last its sapping currents reached the caverns of the ground waters and joined with them in digging a deeper abyss. Finally its whole bulk emptied into the hollow hills and left the old bed toward the ocean dry. Much of the later city as we now found it had been built over that former bed. The Old Ones, understanding what had happened, and exercising their always keen artistic sense, had carved into ornate pylons those headlands of the foothills where the great stream began its descent into eternal darkness.
