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 500,000 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 shewed 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-ridged 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 of 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 shewed 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 aërial 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 connexion 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 connexion with this place.
VI.
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 differences 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 100 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 giganticism 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
