Maps evidently shewing the Carboniferous world of an hundred million or more years ago displayed significant rifts and chasms destined later to separate Africa from the once continuous realms of Europe (then the Valusia of hellish primal legend), Asia, the Americas, and the antarctic continent. Other charts — and most significantly one in connexion with the founding fifty million years ago of the vast dead city around us — shewed all the present continents well differentiated. And in the latest discoverable specimen — dating perhaps from the Pliocene age — the approximate world of today appeared quite clearly despite the linkage of Alaska with Siberia, of North America with Europe through Greenland, and of South America with the antarctic continent through Graham Land. In the Carboniferous map the whole globe — ocean floor and rifted land mass alike — bore symbols of the Old Ones’ vast stone cities, but in the later charts the gradual recession toward the antarctic became very plain. The final Pliocene specimen shewed no land cities except on the antarctic continent and the tip of South America, nor any ocean cities north of the fiftieth parallel of South Latitude. Knowledge and interest in the northern world, save for a study of coast-lines probably made during long exploration flights on those fan-like membraneous wings, had evidently declined to zero among the Old Ones.
Destruction of cities through the upthrust of mountains, the centrifugal rending of continents, the seismic convulsions of land or sea-bottom, and other natural causes was a matter of common record; and it was curious to observe how fewer and fewer replacements were made as the ages wore on. The vast dead megalopolis that yawned around us seemed to be the last general centre of the race; built early in the Cretaceous age after a titanic earth-buckling had obliterated a still vaster predecessor not far distant. It appeared that this general region was the most sacred spot of all, where reputedly the first Old Ones had settled on a primal sea-bottom. In the new city — many of whose features we could recognise in the sculptures, but which stretched fully an hundred miles along the mountain-range in each direction beyond the farthest limits of our aërial survey — there were reputed to be preserved certain sacred stones forming part of the first sea-bottom city, which were thrust up to light after long epochs in the course of the general crumpling of strata.

Naturally, Danforth and I studied with especial interest and a peculiarly personal sense of awe everything pertaining to the immediate district in which we were. Of this local material there was naturally a vast abundance; and on the tangled ground level of the city we were lucky enough to find a house of very late date whose walls, though somewhat damaged by a neighbouring rift, contained sculptures of decadent workmanship carrying the story of the region much beyond the period of the Pliocene map whence we derived our last general glimpse of the pre-human world. This was the last place we examined in detail, since what we found there gave us a fresh immediate objective.
Certainly, we were in one of the strangest, weirdest, and most terrible of all the corners of earth’s globe. Of all existing lands it was infinitely the most ancient; and the conviction grew upon us that this hideous upland must indeed be the fabled nightmare plateau of Leng which even the mad author of the Necronomicon was reluctant to discuss. The great mountain chain was tremendously long — starting as a low range at Luitpold Land on the coast of Weddell Sea and virtually crossing the entire continent. The really high part stretched in a mighty arc from about Latitude 82°, E. Longitude 60° to Latitude 70°, E. Longitude 115°, with its concave side toward our camp and its seaward end in the region of that long, ice-locked coast whose hills were glimpsed by Wilkes and Mawson at the Antarctic Circle.
Yet even more monstrous exaggerations of Nature seemed disturbingly close at hand. I have said that these peaks are higher than the Himalayas, but the sculptures forbid me to say that they are earth’s highest. That grim honour is beyond doubt reserved for something which half the sculptures hesitated to record at all, whilst others approached it with obvious repugnance and trepidation. It seems that there was one part of the ancient land — the first part that ever rose from the waters after the earth had flung off the moon and the Old Ones had seeped down from the stars — which had come to be shunned as vaguely and namelessly evil. Cities built there had crumbled before their time, and had been found suddenly deserted. Then when the first great earth-buckling had convulsed the region in the Comanchian age, a frightful line of peaks had shot suddenly up amidst the most appalling din and chaos — and earth had received her loftiest and most terrible mountains.
