The outside world knew, of course, of our program, and was told also of Lake’s strange and dogged insistence on a westward – or rather, northwestward – prospecting trip before our radical shift to the new base. It seems that he had pondered a great deal, and with alarmingly radical daring, over that triangular striated marking in the slate; reading into it certain contradictions in nature and geological period which whetted his curiosity to the utmost, and made him avid to sink more borings and blastings in the west-stretching formation to which the exhumed fragments evidently belonged. He was strangely convinced that the marking was the print of some bulky, unknown, and radically unclassifiable organism of considerably advanced evolution, notwithstanding that the rock which bore it was of so vastly ancient a date – Cambrian if not actually pre-Cambrian – as to preclude the probable existence not only of all highly evolved life, but of any life at all above the unicellular or at most the trilobite stage. These fragments, with their odd marking, must have been five hundred million to a thousand million years old.

Popular imagination, I judge, responded actively to our wireless bulletins of Lake’s start northwestward into regions never trodden by human foot or penetrated by human imagination, though we did not mention his wild hopes of revolutionizing the entire sciences of biology and geology. His preliminary sledging and boring journey of January 11th to 18th with Pabodie and five others – marred by the loss of two dogs in an upset when crossing one of the great pressure ridges in the ice – had brought up more and more of the Archaean slate; and even I was interested by the singular profusion of evident fossil markings in that unbelievably ancient stratum. These markings, however, were of very primitive life forms involving no great paradox except that any life forms should occur in rock as definitely pre-Cambrian as this seemed to be; hence I still failed to see the good sense of Lake’s demand for an interlude in our time-saving program – an interlude requiring the use of all four planes, many men, and the whole of the expedition’s mechanical apparatus. I did not, in the end, veto the plan, though I decided not to accompany the northwestward party despite Lake’s plea for my geological advice. While they were gone, I would remain at the base with Pabodie and five men and work out final plans for the eastward shift. In preparation for this transfer, one of the planes had begun to move up a good gasoline supply from McMurdo Sound; but this could wait temporarily. I kept with me one sledge and nine dogs, since it is unwise to be at any time without possible transportation in an utterly tenantless world of aeon-long death.
Lake’s sub-expedition into the unknown, as everyone will recall, sent out its own reports from the shortwave transmitters on the planes; these being simultaneously picked up by our apparatus at the southern base and by the Arkham at McMurdo Sound, whence they were relayed to the outside world on wave lengths up to fifty meters. The start was made January 22nd at 4 A. M., and the first wireless message we received came only two hours later, when Lake spoke of descending and starting a small-scale ice-melting and bore at a point some three hundred miles away from us. Six hours after that a second and very excited message told of the frantic, beaver-like work whereby a shallow shaft had been sunk and blasted, culminating in the discovery of slate fragments with several markings approximately like the one which had caused the original puzzlement.
Three hours later a brief bulletin announced the resumption of the flight in the teeth of a raw and piercing gale; and when I dispatched a message of protest against further hazards, Lake replied curtly that his new specimens made any hazard worth taking. I saw that his excitement had reached the point of mutiny, and that I could do nothing to check this headlong risk of the whole expedition’s success; but it was appalling to think of his plunging deeper and deeper into that treacherous and sinister white immensity of tempests and unfathomed mysteries which stretched off for some fifteen hundred miles to the half-known, half-suspected coast line of Queen Mary and Knox Lands.
Then, in about an hour and a half more, came that doubly excited message from Lake’s moving plane, which almost reversed my sentiments and made me wish I had accompanied the party:
“10:05 P. M. On the wing. After snowstorm, have spied mountain range ahead higher than any hitherto seen. May equal Himalayas, allowing for height of plateau. Probable Latitude 76° 15’, Longitude 113° 10’ E. Reaches far as can see to right and left. Suspicion of two smoking cones. All peaks black and bare of snow. Gale blowing off them impedes navigation.”
After that Pabodie, the men and I hung breathlessly over the receiver. Thought of this titanic mountain rampart seven hundred miles away inflamed our deepest sense of adventure; and we rejoiced that our expedition, if not ourselves personally, had been its discoverers. In half an hour Lake called us again:
“Moulton’s plane forced down on plateau in foothills, but nobody hurt and perhaps can repair. Shall transfer essentials to other three for return or further moves if necessary, but no more heavy plane travel needed just now. Mountains surpass anything in imagination. Am going up scouting in Carroll’s plane, with all weight out. You can’t imagine anything like this. Highest peaks must go over thirty-five thousand feet. Everest out of the running. Atwood to work out height with theodolite while Carroll and I go up. Probably wrong about cones, for formations look stratified. Possibly pre-Cambrian slate with other strata mixed in. Queer skyline effects – regular sections of cubes clinging to highest peaks. Whole thing marvelous in red-gold light of low sun. Like land of mystery in a dream or gateway to forbidden world of untrodden wonder. Wish you were here to study.”
Though it was technically sleeping-time, not one of us listeners thought for a moment of retiring. It must have been a good deal the same at McMurdo Sound, where the supply cache and the Arkham were also getting the messages; for Captain Douglas gave out a call congratulating everybody on the important find, and Sherman, the cache operator, seconded his sentiments. We were sorry, of course, about the damaged aeroplane, but hoped it could be easily mended. Then, at 11 P. M., came another call from Lake:
“Up with Carroll over highest foothills. Don’t dare try really tall peaks in present weather, but shall later. Frightful work climbing, and hard going at this altitude, but worth it. Great range fairly solid, hence can’t get any glimpses beyond. Main summits exceed Himalayas, and very queer. Range looks like pre-Cambrian slate, with plain signs of many other upheaved strata. Was wrong about volcanism. Goes farther in either direction than we can see. Swept clear of snow above about twenty-one thousand feet. Odd formations on slopes of highest mountains. Great low square blocks with exactly vertical sides, and rectangular lines of low, vertical ramparts, like the old Asian castles clinging to steep mountains in Roerich’s paintings. Impressive from distance. Flew close to some, and Carroll thought they were formed of smaller separate pieces, but that is probably weathering. Most edges crumbled and rounded off as if exposed to storms and climate changes for millions of years. Parts, especially upper parts, seem to be of lighter-colored rock than any visible strata on slopes proper, hence of evidently crystalline origin. Close flying shows many cave-mouths, some unusually regular in outline, square or semicircular. You must come and investigate. Think I saw rampart squarely on top of one peak. Height seems about thirty thousand to thirty-five thousand feet. Am up twenty-one thousand, five hundred myself, in devilish, gnawing cold. Wind whistles and pipes through passes and in and out of caves, but no flying danger so far.”
From then on for another half hour Lake kept up a running fire of comment, and expressed his intention of climbing some of the peaks on foot. I replied that I would join him as soon as he could send a plane, and that Pabodie and I would work out the best gasoline plan – just where and how to concentrate our supply in view of the expedition’s altered character. Obviously, Lake’s
