This rampart, shaped like a star and perhaps three hundred feet from point to point, was built of Jurassic sandstone blocks of irregular size, averaging 6 × 8 feet in surface. There was a row of arched loopholes or windows about four feet wide and five feet high, spaced quite symmetrically along the points of the star and at its inner angles, and with the bottoms about four feet from the glaciated surface. Looking through these, we could see that the masonry was fully five feet thick, that there were no partitions remaining within, and that there were traces of banded carvings or bas-reliefs on the interior walls - facts we had indeed guessed before, when flying low over this rampart and others like it. Though lower parts must have originally existed, all traces of such things were now wholly obscured by the deep layer of ice and snow at this point.
We crawled through one of the windows and vainly tried to decipher the nearly effaced mural designs, but did not attempt to disturb the glaciated floor. Our orientation flights had indicated that many buildings in the city proper were less ice-choked, and that we might perhaps find wholly clear interiors leading down to the true ground level if we entered those structures still roofed at the top. Before we left the rampart we photographed it carefully, and studied its mortarless Cyclopean masonry with complete bewilderment. We wished that Pabodie were present, for his engineering knowledge might have helped us guess how such titanic blocks could have been handled in that unbelievably remote age when the city and its outskirts were built up.
The half-mile walk downhill to the actual city, with the upper wind shrieking vainly and savagely through the skyward peaks in the background, was something of which the smallest details will always remain engraved on my mind. Only in fantastic nightmares could any human beings but Danforth and me conceive such optical effects. Between us and the churning vapours of the west lay that monstrous tangle of dark stone towers, its outré and incredible forms impressing us afresh at every new angle of vision. It was a mirage in solid stone, and were it not for the photographs I would still doubt that such a thing could be. The general type of masonry was identical with that of the rampart we had examined; but the extravagant shapes which this masonry took in its urban manifestations were past all description.
Even the pictures illustrate only one or two phases of its endless variety, preternatural massiveness, and utterly alien exoticism. There were geometrical forms for which an Euclid would scarcely find a name - cones of all degrees of irregularity and truncation, terraces of every sort of provocative disproportion, shafts with odd bulbous enlargements, broken columns in curious groups, and five-pointed or five-ridged arrangements of mad grotesqueness. As we drew nearer we could see beneath certain transparent parts of the ice sheet, and detect some of the tubular stone bridges that connected the crazily sprinkled structures at various heights. Of orderly streets there seemed to be none, the only broad open swath being a mile to the left, where the ancient river had doubtless flowed through the town into the mountains.
Our field glasses showed the external, horizontal bands of nearly effaced sculptures and dot groups to be very prevalent, and we could half imagine what the city must once have looked like - even though most of the roofs and tower tops had necessarily perished. As a whole, it had been a complex tangle of twisted lanes and alleys, all of them deep canyons, and some little better than tunnels because of the overhanging masonry or overarching bridges. Now, outspread below us, it loomed like a dream fantasy against a westward mist through whose northern end the low, reddish antarctic sun of early afternoon was struggling to shine; and when, for a moment, that sun encountered a denser obstruction and plunged the scene into temporary shadow, the effect was subtly menacing in a way I can never hope to depict. Even the faint howling and piping of the unfelt wind in the great mountain passes behind us took on a wilder note of purposeful malignity. The last stage of our descent to the town was unusually steep and abrupt, and a rock outcropping at the edge where the grade changed led us to think that an artificial terrace had once existed there. Under the glaciation, we believed, there must be a flight of steps or its equivalent.
When at last we plunged into the town itself, clambering over fallen masonry and shrinking from the oppressive nearness and dwarfing height of omnipresent crumbling and pitted walls, our sensations again became such that I marvel at the amount of self-control we retained. Danforth was frankly jumpy, and began making some offensively irrelevant speculations about the horror at the camp - which I resented all the more because I could not help sharing certain conclusions forced upon us by many features of this morbid survival from nightmare antiquity. The speculations worked on his imagination, too; for in one place - where a debris-littered alley turned a sharp corner - he insisted that he saw faint traces of ground markings which he did not like; whilst elsewhere he stopped to listen to a subtle, imaginary sound from some undefined point - a muffled musical piping, he said, not unlike that of the wind in the mountain caves, yet somehow disturbingly different. The ceaseless five-pointedness of the surround in architecture and of the few distinguishable mural arabesques had a dimly sinister suggestiveness we could not escape, and gave us a touch of terrible subconscious certainty concerning the primal entities which had reared and dwelt in this unhallowed place.
Nevertheless, our scientific and adventurous souls were not wholly dead, and we mechanically carried out our programme of chipping specimens from all the different rock types represented in the masonry. We wished a rather full set in order to draw better conclusions regarding the age of the place. Nothing in the great outer walls seemed to date from later than the Jurassic and Comanchian periods, nor was any piece of stone in the entire place of a greater recency than the Pliocene Age. In stark certainty, we were wandering amidst a death which had reigned at least five hundred thousand years, and in all probability even longer.
As we proceeded through this maze of stone-shadowed twilight we stopped at all available apertures to study interiors and investigate entrance possibilities. Some were above our reach, whilst others led only into ice-choked ruins as unroofed and barren as the rampart on the hill. One, though spacious and inviting, opened on a seemingly bottomless abyss without visible means of descent. Now and then we had a chance to study the petrified wood of a surviving shutter, and were impressed by the fabulous antiquity implied in the still discernible grain. These things had come from Mesozoic gymnosperms and conifers - especially Cretaceous cycads - and from fan palms and early angiosperms of plainly Tertiary date. Nothing definitely later than the Pliocene could be discovered. In the placing of these shutters - whose edges showed the former presence of queer and long-vanished hinges - usage seemed to be varied - some being on the outer and some on the inner side of the deep embrasures. They seemed to have become wedged in place, thus surviving the rusting of their former and probably metallic fixtures and fastenings.
After a time we came across a row of windows - in the bulges of a colossal five-edged cone of undamaged apex - which led into a vast, well-preserved room with stone flooring; but these were too high in the room to permit descent without a rope. We had a rope with us, but did not wish to bother with this twenty-foot drop unless obliged to - especially in this thin plateau air where great demands were made upon the heart action. This enormous room was probably a hall or concourse of some sort, and our electric torches showed bold, distinct, and potentially startling sculptures arranged round the walls in broad, horizontal bands separated by equally broad strips of conventional arabesques. We took careful note of this spot, planning to enter here unless a more easily gained interior were encountered.
Finally, though, we did encounter exactly the opening we wished; an archway about six feet wide and ten feet high, marking the former end of an aerial bridge which had spanned an alley about five feet above the present level of glaciation. These archways, of course, were flush with upper-story floors, and in this case one of the floors still existed. The building thus accessible was a series of rectangular terraces on our left facing westward. That across
the alley, where the other archway yawned, was a decrepit cylinder with no windows and with a curious bulge about ten feet above the aperture. It was totally dark inside, and the archway seemed to open on a well of illimitable emptiness.
Heaped debris made the entrance to the vast left-hand building doubly easy, yet for a moment we hesitated before taking advantage of the long-wished chance. For though we had penetrated into this tangle of archaic mystery, it required fresh resolution to carry us actually inside a complete and surviving building of a fabulous elder world whose nature was becoming more and more hideously plain to us. In the end, however, we made the plunge, and scrambled up over the rubble into the gaping embrasure. The floor beyond was of great slate slabs, and seemed to form the outlet of a long, high corridor with sculptured walls.
Observing the many inner archways which led off from it, and realising the probable complexity of the nest of apartments within, we decided that we must begin our system of hare-and-hound trail blazing. Hitherto our compasses, together with frequent glimpses of the vast mountain range between the towers in our rear, had been enough to prevent our losing our way; but from now on, the artificial substitute would be necessary. Accordingly we reduced our extra paper to shreds of suitable size, placed these in a bag to be carried by Danforth, and prepared to use them as economically as safety would allow. This method would probably gain us immunity from straying, since there did not appear to be any strong air currents inside the primordial masonry. If such should develop, or if our paper supply should give out, we could of course fall back on the more secure though more tedious and retarding method of rock chipping.
Just how extensive a territory we had opened up, it was impossible to guess without a trial. The close and frequent connection of the different buildings made it likely that we might cross from one to another on bridges underneath the ice, except where impeded by local collapses and geologic rifts, for very little glaciation seemed to have entered the massive constructions. Almost all the areas of transparent ice had revealed the submerged windows as tightly shuttered, as if the town had been left in that uniform state until the glacial sheet came to crystallise the lower part for all succeeding time. Indeed, one gained a curious impression that this place had been deliberately closed and deserted in some dim, bygone aeon, rather than overwhelmed by any sudden calamity or even gradual decay. Had the coming of the ice been foreseen, and had a nameless population left en masse to seek a less doomed abode? The precise physiographic conditions attending the formation of the ice sheet at this point would have to wait for later solution. It had not, very plainly, been a grinding drive. Perhaps the pressure of accumulated snows had been responsible, and perhaps some flood from the river, or from the bursting of some ancient glacial dam in the great range, had helped to create the special state now observable. Imagination could conceive almost anything in connection with this place.

It would be cumbrous to give a detailed, consecutive account of our wanderings inside that cavernous, aeon-dead honeycomb of primal masonry - that monstrous lair of elder secrets which now echoed for the first time, after uncounted epochs, to the tread of human feet. This is especially true because so much of the horrible drama and revelation came from a mere study of the omnipresent mural carvings. Our flashlight photographs of those carvings will do much toward proving the truth of what we are now disclosing, and it is lamentable that we had not a larger film supply with us. As it was, we made crude notebook sketches of certain salient features after all our films were used up.
The building which we had entered was one of great size and elaborateness, and gave us an impressive notion of the architecture of that nameless geologic past. The inner partitions were less massive than the outer walls, but on the lower levels were excellently preserved. Labyrinthine complexity, involving curiously irregular difference in floor levels, characterised the entire arrangement and we should certainly have been lost at the very outset but for the trail of torn paper left behind us. We decided to explore the more decrepit upper parts first of all, hence climbed aloft in the maze for a distance of some one hundred feet, to where the topmost tier of chambers yawned snowily and ruinously open to the polar sky. Ascent was effected over the steep, transversely ribbed stone ramps or inclined planes which everywhere served in lieu of stairs. The rooms we encountered were of all imaginable shapes and proportions, ranging from five-pointed stars to triangles and perfect cubes. It might be safe to say that their general average was about 30 × 30 feet in floor area, and 20 feet in height, though many larger apartments existed. After thoroughly examining the upper regions and the glacial level we descended, story by story, into the submerged part, where indeed we soon saw we were in a continuous maze of connected chambers and passages probably leading over unlimited areas outside this particular building. The Cyclopean massiveness and gigantism of everything about us became curiously oppressive; and there was something vaguely but deeply unhuman in all the contours, dimensions, proportions, decorations, and constructional nuances of the blasphemously archaic stonework. We soon realised, from what the carvings revealed, that this monstrous city was many million years old.
We cannot yet explain the engineering principles used in the anomalous balancing and adjustment of the vast rock masses, though the function of the arch was clearly much relied on. The rooms we visited were wholly bare of all portable contents, a circumstance which sustained our belief in the city’s deliberate desertion. The prime decorative feature was the almost universal system of mural sculpture, which tended to run in continuous horizontal bands three feet wide and arranged from floor to ceiling in alternation with bands of equal width given over to geometrical arabesques. There were exceptions to this rule of arrangement, but its preponderance was overwhelming. Often, however, a series of smooth cartouches containing oddly patterned groups of dots would be sunk along one of the arabesque bands.
The technique, we soon saw, was mature, accomplished, and aesthetically evolved to the highest degree of civilised mastery, though utterly alien in every detail to any known art tradition of the human race. In delicacy of execution no sculpture I have ever seen could approach it. The minutest details of elaborate vegetation, or of animal life, were rendered with astonishing vividness despite the bold scale of the carvings; whilst the conventional designs were marvels of skilful intricacy. The arabesques displayed a profound use of mathematical principles, and were made up of obscurely symmetrical curves and angles based on the quantity of five. The pictorial bands followed a highly formalised tradition, and involved a peculiar treatment of perspective, but had an artistic force that moved us profoundly notwithstanding the intervening gulf of vast geologic periods. Their method of design hinged on a singular juxtaposition of the cross section with the two-dimensional silhouette, and embodied an analytical psychology beyond that of any known race of antiquity. It is useless to try to compare this art with any represented in our museums. Those who see our photographs will probably find its closest analogue in certain grotesque conceptions of the most daring futurists.
The arabesque tracery consisted altogether of depressed lines, whose depth on unweathered walls varied from one to two inches. When cartouches with dot groups appeared - evidently as inscriptions in some unknown and primordial language and alphabet - the depression of the smooth surface was perhaps an inch and a half, and of the dots perhaps a half inch more. The pictorial bands were in countersunk low relief, their background being depressed about two inches from the original wall surface. In some specimens marks of a former coloration could be detected, though for the most part the untold aeons had disintegrated and banished any pigments which may have been applied. The more one studied the marvellous technique the more one admired the things. Beneath their strict conventionalisation one could grasp the minute and accurate observation and graphic skill of the artists; and indeed, the very conventions themselves served to symbolise and accentuate the real essence or vital differentiation of every object delineated. We felt, too, tha
t besides these recognisable excellences there were others lurking beyond the reach of our perceptions. Certain touches here and there gave vague hints of latent symbols and stimuli which another mental and emotional background, and a fuller or different sensory equipment, might have made of profound and poignant significant to us.
The subject matter of the sculptures obviously came from the life of the vanished epoch of their creation, and contained a large proportion of evident history. It is this abnormal historic-mindedness of the primal race - a chance circumstance operating, through coincidence, miraculously in our favour - which made the carvings so awesomely informative to us, and which caused us to place their photography and transcription above all other considerations. In certain rooms the dominant arrangement was varied by the presence of maps, astronomical charts, and other scientific designs of an enlarged scale - these things giving a naive and terrible corroboration to what we gathered from the pictorial friezes and dadoes. In hinting at what the whole revealed, I can only hope that my account will not arouse a curiosity greater than sane caution on the part of those who believe me at all. It would be tragic if any were to be allured to that realm of death and horror by the very warning meant to discourage them.
