But the salient object of the place was the titanic stone ramp which, eluding the archways by a sharp turn outward into the open floor, wound spirally up the stupendous cylindrical wall like an inside counterpart of those once climbing outside the monstrous towers or ziggurats of antique Babylon. Only the rapidity of our flight, and the perspective which confounded the descent with the tower's inner wall, had prevented our noticing this feature from the air, and thus caused us to seek another avenue to the subglacial level. Pabodie might have been able to tell what sort of engineering held it in place, but Danforth and I could merely admire and marvel. We could see mighty stone corbels and pillars here and there, but what we saw seemed inadequate to the function performed. The thing was excellently preserved up to the present top of the tower – a highly remarkable circumstance in view of its exposure – and its shelter had done much to protect the bizarre and disturbing cosmic sculptures on the walls.

As we stepped out into the awesome half daylight of this monstrous cylinder bottom – fifty million years old, and without doubt the most primally ancient structure ever to meet our eyes – we saw that the ramp-traversed sides stretched dizzily up to a height of fully sixty feet. This, we recalled from our aerial survey, meant an outside glaciation of some forty feet; since the yawning gulf we had seen from the plane had been at the top of an approximately twenty-foot mound of crumbled masonry, somewhat sheltered for three-fourths of its circumference by the massive curving walls of a line of higher ruins. According to the sculptures, the original tower had stood in the center of an immense circular plaza, and had been perhaps five hundred or six hundred feet high, with tiers of horizontal disks near the top, and a row of needlelike spires along the upper rim. Most of the masonry had obviously toppled outward rather than inward – a fortunate happening, since otherwise the ramp might have been shattered and the whole interior choked. As it was, the ramp showed sad battering; whilst the choking was such that all the archways at the bottom seemed to have been recently cleared.

It took us only a moment to conclude that this was indeed the route by which those others had descended, and that this would be the logical route for our own ascent despite the long trail of paper we had left elsewhere. The tower's mouth was no farther from the foothills and our waiting plane than was the great terraced building we had entered, and any further subglacial exploration we might make on this trip would lie in this general region. Oddly, we were still thinking about possible later trips – even after all we had seen and guessed. Then, as we picked our way cautiously over the debris of the great floor, there came a sight which for the time excluded all other matters.

It was the neatly huddled array of three sledges in that farther angle of the ramp's lower and outward-projecting course which had hitherto been screened from our view. There they were – the three sledges missing from Lake's camp – shaken by a hard usage which must have included forcible dragging along great reaches of snowless masonry and debris, as well as much hand portage over utterly unnavigable places. They were carefully and intelligently packed and strapped, and contained things memorably familiar enough: the gasoline stove, fuel cans, instrument cases, provision tins, tarpaulins obviously bulging with books, and some bulging with less obvious contents – everything derived from Lake's equipment.

Alfer what we had found in that other room, we were in a measure prepared for this encounter. The really great shock came when we stepped over and undid one tarpaulin whose outlines had peculiarly disquieted us. It seems that others as well as Lake had been interested in collecting typical specimens; for there were two here, both stiffly frozen, perfectly preserved, patched with adhesive plaster where some wounds around the neck had occurred, and wrapped with care to prevent further damage. They were the bodies of young Gedney and the missing dog.

Many people will probably judge us callous as well as mad for thinking about the northward tunnel and the abyss so soon after our somber discovery, and I am not prepared to say that we would have immediately revived such thoughts but for a specific circumstance which broke in upon us and set up a whole new train of speculations. We had replaced the tarpaulin over poor Gedney and were standing in a kind of mute bewilderment when the sounds finally reached our consciousness – the first sounds we had heard since descending out of the open where the mountain wind whined faintly from its unearthly heights. Well-known and mundane though they were, their presence in this remote world of death was more unexpected and unnerving than any grotesque or fabulous tones 'could possibly have been – since they gave a fresh upsetting to all our notions of cosmic harmony.

Had it been some trace of that bizarre musical piping over a wide range which Lake's dissection report had led us to expect in those others – and which, indeed, our overwrought fancies had been reading into every wind howl we had heard since coming on the camp horror – it would have had a kind of hellish congruity with the aeon-dead region around us. A voice from other epochs belongs in a graveyard of other epochs. As it was, however, the noise shattered all our profoundly seated adjustments – all our tacit acceptance of the inner antarctic as a waste utterly and irrevocably void of every vestige of normal life. What we heard was not the fabulous note of any buried blasphemy of elder earth from whose supernal toughness an age-denied polar sun had evoked a monstrous response. Instead, it was a thing so mockingly normal and so unerringly familiarized by our sea days off Victoria Land and our camp days at McMurdo Sound that we shuddered to think of it here, where such things ought not to be. To be brief – it was simply the raucous squawking of a penguin.

The muffled sound floated from subglacial recesses nearly opposite to the corridor whence we had come – regions manifestly in the direction of that other tunnel to the vast abyss. The presence of a living water bird in such a direction – in a world whose surface was one of age-long and uniform lifelessness – could lead to only one conclusion; hence our first thought was to verify the objective reality of the sound. It was, indeed, repeated, and seemed at times to come from more than one throat. Seeking its source, we entered an archway from which much debris had been cleared; resuming our trail blazing – with an added paper supply taken with curious repugnance from one of the tarpaulin bundles on the sledges – when we left daylight behind.

As the glaciated floor gave place to a litter of detritus, we plainly discerned some curious, dragging tracks; and once Danforth found a distinct print of a sort whose description would be only too superfluous. The course indicated by the penguin cries was precisely what our map and compass prescribed as an approach to the more northerly tunnel mouth, and we were glad to find that a bridgeless thoroughfare on the ground and basement levels seemed open. The tunnel, according to the chart, ought to start from the basement of a large pyramidal structure which we seemed vaguely to recall from our aerial survey as remarkably well-preserved. Along our path the single torch showed a customary profusion of carvings, but we did not pause to examine any of these.

Suddenly a bulky white shape loomed up ahead of us, and we flashed on the second torch. It is odd how wholly this new quest had turned our minds from earlier fears of what might lurk near. Those other ones, having left their supplies in the great circular place, must have planned to return after their scouting trip toward or into the abyss; yet we had now discarded all caution concerning them as completely as if they had never existed. This white, waddling thing was fully six feet high, yet we seemed to realize at once that it was not one of those others. They were larger and dark, and, according to the sculptures, their motion over land surfaces was a swift, assured matter despite the queerness of their sea-born tentacle equipment. But to say that the white thing did not profoundly frighten us would be vain. We were indeed clutched for an instant by primitive dread almost sharper than the worst of our reasoned fears regarding those others. Then came a flash of anticlimax as the white shape sidled into a lateral archway to our left to join two others of its kind which had summoned it in raucous tones. For it was only a penguin – albeit of a huge, unknown species larger than the greatest of the known king penguins, and monstrous in its combined albinism and virtual eyelessness.
