The torch, flashing over the grotesquely carved walls of the blocked corridor in which we stood, showed several doorways in various states of obstruction; and from one of them the gasoline odor-quite submerging that other hint of odor – came with especial distinctness. As we looked more steadily, we saw that beyond a doubt there had been a slight and recent clearing away of debris from that particular opening. Whatever the lurking horror might be, we believed the direct avenue toward it was now plainly manifest. I do not think anyone will wonder that we waited an appreciable time before making any further motion.

And yet, when we did venture inside that black arch, our first impression was one of anticlimax. For amidst the littered expanse of that sculptured Crypt – a perfect cube with sides of about twenty feet – there remained no recent object of instantly discernible size; so that we looked instinctively, though in vain, for a farther doorway. In another moment, however, Danforth's sharp vision had descried a place where the floor debris had been disturbed; and we turned on both torches full strength. Though what we saw in that light was actually simple and trifling, I am none the less reluctant to tell of it because of what it implied. It was a rough leveling of the debris, upon which several small objects lay carelessly scattered, and at one corner of which a considerable amount of gasoline must have been spilled lately enough to leave a strong odor even at this extreme superplateau altitude. In other words, it could not be other than a sort of camp – a camp made by questing beings who, like us, had been turned back by the unexpectedly choked way to the abyss.

Let me be plain. The scattered objects were, so far as substance was concerned, all from Lake's camp; and consisted of tin cans as queerly opened as those we had seen at that ravaged place, many spent matches, three illustrated books more or less curiously smudged, an empty ink bottle with its pictorial and instructional carton, a broken fountain pen, some oddly snipped fragments of fur and tent cloth, a used electric battery with circular of directions, a folder that came with our type of tent heater, and a sprinkling of crumpled papers. It was all bad enough but when we smoothed out the papers and looked at what was on them, we felt we had come to the worst. We had found certain inexplicably blotted papers at the camp which might have prepared us, yet the effect of the sight down there in the prehuman vaults of a nightmare city was almost too much to bear.

A mad Gedney might have made the groups of dots in imitation of those found on the greenish soapstones, just as the dots on those insane five-pointed grave mounds might have been made; and he might conceivably have prepared rough, hasty sketches – varying in their accuracy or lack of it – which outlined the neighboring parts of the city and traced the way from a circularly represented place outside our previous route – a place we identified as a great cylindrical tower in the carvings and as a vast circular gulf glimpsed in our aerial survey – to the present five-pointed structure and the tunnel mouth therein.

He might, I repeat, have prepared such sketches; for those before us were quite obviously compiled, as our own had been, from late sculptures somewhere in the glacial labyrinth, though not from the ones which we had seen and used. But what the art-blind bungler could never have done was to execute those sketches in a strange and assured technique perhaps superior, despite haste and carelessness, to any of the decadent carvings from which they were taken – the characteristic and unmistakable technique of the Old Ones themselves in the dead city's heyday.

There are those who will say Danforth and I were utterly mad not to flee for our lives after that; since our conclusions were now – notwithstanding their wildness – completely fixed, and of a nature I need not even mention to those who have read my account as far as this. Perhaps we were mad – for have I not said those horrible peaks were mountains of madness? But I think I can detect something of the same spirit – albeit in a less extreme form – in the men who stalk deadly beasts through African jungles to photograph them or study their habits. Half paralyzed with terror though we were, there was nevertheless fanned within us a blazing flame of awe and curiosity which triumphed in the end.

Of course we did not mean to face that – or those – which we knew had been there, but we felt that they must be gone by now. They would by this time have found the other neighboring entrance to the abyss, and have passed within, to whatever night-black fragments of the past might await them in the ultimate gulf – the ultimate gulf they had never seen. Or if that entrance, too, was blocked, they would have gone on to the north seeking another. They were, we remembered, partly independent of light.

Looking back to that moment, I can scarcely recall just what precise form our new emotions took – just what change of immediate objective it was that so sharpened our sense of expectancy. We certainly did not mean to face what we feared – yet I will not deny that we may have had a lurking, unconscious wish to spy certain things from some hidden vantage point. Probably we had not given up our zeal to glimpse the abyss itself, though there was interposed a new goal in the form of that great circular place shown on the crumpled sketches we had found. We had at once recognized it as a monstrous cylindrical tower figuring in the very earliest carvings, but appearing only as a prodigious round aperture from above. Something about the impressiveness of its rendering, even in these hasty diagrams, made us think that its subglacial levels must still form a feature of peculiar importance. Perhaps it embodied architectural marvels as yet unencountered by us. It was certainly of incredible age according to the sculptures in which it figured – being indeed among the first things built in the city. Its carvings, if preserved, could not but be highly significant. Moreover, it might form a good present link with the upper world – a shorter route than the one we were so carefully blazing, and probably that by which those others had descended.

At any rate, the thing we did was to study the terrible sketches – which quite perfectly confirmed our own – and start back over the indicated course to the circular place; the course which our nameless predecessors must have traversed twice before us. The other neighboring gate to the abyss would lie beyond that. I need not speak of our journey – during which we continued to leave an economical trail of paper – for it was precisely the same in kind as that by which we had reached the cul-de-sac; except that it tended to adhere more closely to the ground level and even descend to basement corridors. Every now and then we could trace certain disturbing marks in the debris or litter underfoot; and after we had passed outside the radius of the gasoline scent, we were again faintly conscious – spasmodically – of that more hideous and more persistent scent. After the way had branched from our former course, we sometimes gave the rays of our single torch a furtive sweep along the walls; noting in almost every case the well-nigh omnipresent sculptures, which indeed seem to have formed a main aesthetic outlet for the Old Ones.

About 9:30 P.M., while traversing a long, vaulted corridor whose increasingly glaciated floor seemed somewhat below the ground level and whose roof grew lower as we advanced, we began to see strong daylight ahead and were able to turn off our torch. It appeared that we were coming to the vast circular place, and that our distance from the upper air could not be very great. The corridor ended in an arch surprisingly low for these megalithic ruins, but we could see much through it even before we emerged. Beyond there stretched a prodigious round space – fully two hundred feet in diameter – strewn with debris and containing many choked archways corresponding to the one we were about to cross. The walls were – in available spaces – boldly sculptured into a spiral band of heroic proportions; and displayed, despite the destructive weathering caused by the openness of the spot, an artistic splendor far beyond anything we had encountered before. The littered floor was quite heavily glaciated, and we fancied that the true bottom lay at a considerably lower depth.
