As I have indicated, Gedney and one dog turned out to be missing in the end. When we came on that terrible shelter we had missed two dogs and two men; but the fairly unharmed dissecting tent, which we entered after investigating the monstrous graves, had something to reveal. It was not as Lake had left it, for the covered parts of the primal monstrosity had been removed from the improvised table. Indeed, we had already realized that one of the six imperfect and insanely buried things we had found – the one with the trace of a peculiarly hateful odor – must represent the collected sections of the entity which Lake had tried to analyze. On and around that laboratory table were strewn other things, and it did not take long for us to guess that those things were the carefully though oddly and inexpertly dissected parts of one man and one dog. I shall spare the feelings of survivors by omitting mention of the man's identity. Lake's anatomical instruments were missing, but there were evidences of their careful cleansing. The gasoline stove was also gone, though around it we found a curious litter of matches. We buried the human parts beside the other ten men; and the canine parts with the other thirty-five dogs. Concerning the bizarre smudges on the laboratory table, and on the jumble of roughly handled illustrated books scattered near it, we were much too bewildered to speculate.

This formed the worst of the camp horror, but other things were equally perplexing. The disappearance of Gedney, the one dog, the eight uninjured biological specimens, the three sledges, and certain instruments, illustrated technical and scientific books, writing materials, electric torches and batteries, food and fuel, heating apparatus, spare tents, fur suits, and the like, was utterly beyond sane conjecture; as were likewise the spatter-fringed ink blots on certain pieces of paper, and the evidences of curious alien fumbling and experimentation around the planes and all other mechanical devices both at the camp and at the boring. The dogs seemed to abhor this oddly disordered machinery. Then, too, there was the upsetting of the larder, the disappearance of certain staples, and the jarringly comical heap of tin cans pried open in the most unlikely ways and at the most unlikely places. The profusion of scattered matches, intact, broken, or spent, formed another minor enigma – as did the two or three tent cloths and fur suits which we found lying about with peculiar and unorthodox slashings conceivably due to clumsy efforts at unimaginable adaptations. The maltreatment of the human and canine bodies, and the crazy burial of the damaged Archaean specimens, were all of a piece with this apparent disintegrative madness. In view of just such an eventuality as the present one, we carefully photographed all the main evidences of insane disorder at the camp; and shall use the prints to buttress our pleas against the departure of the proposed Starkweather-Moore Expedition.

Our first act after finding the bodies in the shelter was to photograph and open the row of insane graves with the five-pointed snow mounds. We could not help noticing the resemblance of these monstrous mounds, with their clusters of grouped dots, to poor Lake's descriptions of the strange greenish soapstones; and when we came on some of the soapstones themselves in the great mineral pile, we found the likeness very close indeed. The whole general formation, it must be made clear, seemed abominably suggestive of the starfish head of the Archaean entities; and we agreed that the suggestion must have worked potently upon the sensitized minds of Lake's overwrought party.

For madness – centering in Gedney as the only possible surviving agent – was the explanation spontaneously adopted by everybody so far as spoken utterance was concerned; though I will not be so naive as to deny that each of us may have harbored wild guesses which sanity forbade him to formulate completely. Sherman, Pabodie, and McTighe made an exhaustive aeroplane cruise over all the surrounding territory in the afternoon, sweeping the horizon with field glasses in quest of Gedney and of the various missing things; but nothing came to light. The party reported that the titan barrier range extended endlessly to right and left alike, without any diminution in height or essential structure. On some of the peaks, though, the regular cube and rampart formations were bolder and plainer, having doubly fantastic similitudes to Roerich-painted Asian hill ruins. The distribution of cryptical cave mouths on the black snow-denuded summits seemed roughly even as far as the range could be traced.

In spite of all the prevailing horrors, we were left with enough sheer scientific zeal and adventurousness to wonder about the unknown realm beyond those mysterious mountains. As our guarded messages stated, we rested at midnight after our day of terror and bafflement – but not without a tentative plan for one or more range-crossing altitude flights in a lightened plane with aerial camera and geologist's outfit, beginning the following morning. It was decided that Danforth and I try it first, and we awaked at 7 A .M. intending an early flight; however, heavy winds – mentioned in our brief, bulletin to the outside world – delayed our start till nearly nine o'clock.

I have already repeated the noncommittal story we told the men at camp – and relayed outside – after our return sixteen hours later. It is now my terrible duty to amplify this account by filling in the merciful blanks with hints of what we really saw in the hidden transmontane world – hints of the revelations which have finally driven Danforth to a nervous collapse. I wish he would add a really frank word about the thing which he thinks he alone saw – even though it was probably a nervous delusion – and which was perhaps the last straw that put him where he is; but he is firm against that. All I can do is to repeat his later disjointed whispers about what set him shrieking as the plane soared back through the wind-tortured mountain pass after that real and tangible shock which I shared. This will form my last word. If the plain signs of surviving elder horrors in what I disclose be not enough to keep others from meddling with the inner antarctic – or at least from prying too deeply beneath the surface of that ultimate waste of forbidden secrets and inhuman, aeon-cursed desolation – the responsibility for unnamable and perhaps immeasurable evils will not be mine.

Danforth and I, studying the notes made by Pabodie in his afternoon flight and checking up with a sextant, had calculated that the lowest available pass in the range lay somewhat to the right of us, within sight of camp, and about twenty-three thousand or twenty-four thousand feet above sea level. For this point, then, we first headed in the lightened plane as we embarked on our flight of discovery. The camp itself, on foothills which sprang from a high continental plateau, was some twelve thousand feet in altitude; hence the actual height increase necessary was not so vast as it might seem. Nevertheless we were acutely conscious of the rarefied air and intense cold as we rose; for, on account of visibility conditions, we had to leave the cabin windows open. We were dressed, of course, in our heaviest furs.

As we drew near the forbidding peaks, dark and sinister above the line of crevasse-riven snow and interstitial glaciers, we noticed more and more the curiously regular formations clinging to the slopes; and thought again of the strange Asian paintings of Nicholas Roerich. The ancient and wind-weathered rock strata fully verified all of Lake's bulletins, and proved that these pinnacles had been towering up in exactly the same way since a surprisingly early time in earth's history – perhaps over fifty million years. How much higher they had once been, it was futile to guess; but everything about this strange region pointed to obscure atmospheric influences unfavorable to change, and calculated to retard the usual climatic processes of rock disintegration.
