The whole tangle was monstrously weathered, and the glacial surface from which the towers projected was strewn with fallen blocks and immemorial debris. Where the glaciation was transparent we could see the lower parts of the gigantic piles, and noticed the ice-preserved stone bridges which connected the different towers at varying distances above the ground. On the exposed walls we could detect the scarred places where other and higher bridges of the same sort had existed. Closer inspection revealed countless largish windows; some of which were closed with shutters of a petrified material originally wood, though most gaped open in a sinister and menacing fashion. Many of the ruins, of course, were roofless, and with uneven though wind-rounded upper edges; whilst others, of a more sharply conical or pyramidal model or else protected by higher surrounding structures, preserved intact outlines despite the omnipresent crumbling and pitting. With the field-glass we could barely make out what seemed to be sculptural decorations in horizontal bands — decorations including those curious groups of dots whose presence on the ancient soapstones now assumed a vastly larger significance.
In many places the buildings were totally ruined and the ice-sheet deeply riven from various geologic causes. In other places the stonework was worn down to the very level of the glaciation. One broad swath, extending from the plateau’s interior to a cleft in the foothills about a mile to the left of the pass we had traversed, was wholly free from buildings; and probably represented, we concluded, the course of some great river which in Tertiary times — millions of years ago — had poured through the city and into some prodigious subterranean abyss of the great barrier range. Certainly, this was above all a region of caves, gulfs, and underground secrets beyond human penetration.
Looking back to our sensations, and recalling our dazedness at viewing this monstrous survival from aeons we had thought pre-human, I can only wonder that we preserved the semblance of equilibrium which we did. Of course we knew that something — chronology, scientific theory, or our own consciousness — was woefully awry; yet we kept enough poise to guide the plane, observe many things quite minutely, and take a careful series of photographs which may yet serve both us and the world in good stead. In my case, ingrained scientific habit may have helped; for above all my bewilderment and sense of menace there burned a dominant curiosity to fathom more of this age-old secret — to know what sort of beings had built and lived in this incalculably gigantic place, and what relation to the general world of its time or of other times so unique a concentration of life could have had.
For this place could be no ordinary city. It must have formed the primary nucleus and centre of some archaic and unbelievable chapter of earth’s history whose outward ramifications, recalled only dimly in the most obscure and distorted myths, had vanished utterly amidst the chaos of terrene convulsions long before any human race we know had shambled out of apedom. Here sprawled a palaeogean megalopolis compared with which the fabled Atlantis and Lemuria, Commoriom and Uzuldaroum, and Olathoë in the land of Lomar are recent things of today — not even of yesterday; a megalopolis ranking with such whispered pre-human blasphemies as Valusia, R’lyeh, Ib in the land of Mnar, and the Nameless City of Arabia Deserta. As we flew above that tangle of stark titan towers my imagination sometimes escaped all bounds and roved aimlessly in realms of fantastic associations — even weaving links betwixt this lost world and some of my own wildest dreams concerning the mad horror at the camp.
The plane’s fuel-tank, in the interest of greater lightness, had been only partly filled; hence we now had to exert caution in our explorations. Even so, however, we covered an enormous extent of ground — or rather, air — after swooping down to a level where the wind became virtually negligible. There seemed to be no limit to the mountain-range, or to the length of the frightful stone city which bordered its inner foothills. Fifty miles of flight in each direction shewed no major change in the labyrinth of rock and masonry that clawed up corpse-like through the eternal ice. There were, though, some highly absorbing diversifications; such as the carvings on the canyon where that broad river had once pierced the foothills and approached its sinking-place in the great range. The headlands at the stream’s entrance had been boldly carved into Cyclopean pylons; and something about the ridgy, barrel-shaped designs stirred up oddly vague, hateful, and confusing semi-remembrances in both Danforth and me.
We also came upon several star-shaped open spaces, evidently public squares; and noted various undulations in the terrain. Where a sharp hill rose, it was generally hollowed out into some sort of rambling stone edifice; but there were at least two exceptions. Of these latter, one was too badly weathered to disclose what had been on the jutting eminence, while the other still bore a fantastic conical monument carved out of the solid rock and roughly resembling such things as the well-known Snake Tomb in the ancient valley of Petra.
