But it was the mountainside tangle of regular cubes, ramparts, and cave mouths which fascinated and disturbed us most. I studied them with a field glass and took aerial photographs while Danforth drove; and at times I relieved him at the controls—though my aviation knowledge was purely an amateur’s—in order to let him use the binoculars.
We could easily see that much of the material of the things was a lightish archaean quartzite, unlike any formation visible over broad areas of the general surface; and that their regularity was extreme and uncanny to an extent which poor Lake had scarcely hinted.
As he had said, their edges were crumbled and rounded from untold aeons of savage weathering; but their preternatural solidity and tough material had saved them from obliteration. Many parts, especially those closest to the slopes, seemed identical in substance with the surrounding rock surface.
The whole arrangement looked like the ruins of Macchu Picchu in the Andes, or the primal foundation walls of Kish as dug up by the Oxford-Field Museum Expedition in 1929; and both Danforth and I obtained that occasional impression of separate Cyclopean blocks which Lake had attributed to his flight-companion Carroll.
How to account for such things in this place was frankly beyond me, and I felt queerly humbled as a geologist. Igneous formations often have strange regularities—like the famous Giants’ Causeway in Ireland—but this stupendous range, despite Lake’s original suspicion of smoking cones, was above all else nonvolcanic in evident structure.
The curious cave mouths, near which the odd formation seemed most abundant, presented another, albeit a lesser puzzle because of their regularity of outline. They were, as Lake’s bulletin had said, often approximately square or semicircular; as if the natural orifices had been shaped to greater symmetry by some magic hand. Their numerousness and wide distribution were remarkable, and suggested that the whole region was honeycombed with tunnels dissolved out of limestone strata.
Such glimpses as we secured did not extend far within the caverns, but we saw that they were apparently clear of stalactites and stalagmites. Outside, those parts of the mountain slopes adjoining the apertures seemed invariably smooth and regular; and Danforth thought that the slight cracks and pittings of the weathering tended toward unusual patterns.
Filled as he was with the horrors and strangenesses discovered at the camp, he hinted that the pittings vaguely resembled those baffling groups of dots sprinkled over the primeval greenish soapstones, so hideously duplicated on the madly conceived snow mounds above those six buried monstrosities.
We had risen gradually in flying over the higher foothills and along toward the relatively low pass we had selected. As we advanced we occasionally looked down at the snow and ice of the land route, wondering whether we could have attempted the trip with the simpler equipment of earlier days.
Somewhat to our surprise we saw that the terrain was far from difficult as such things go; and that despite the crevasses and other bad spots it would not have been likely to deter the sledges of a Scott, a Shackleton, or an Amundsen. Some of the glaciers appeared to lead up to wind-bared passes with unusual continuity, and upon reaching our chosen pass we found that its case formed no exception.
Our sensations of tense expectancy as we prepared to round the crest and peer out over an untrodden world can hardly be described on paper; even though we had no cause to think the regions beyond the range essentially different from those already seen and traversed. The touch of evil mystery in these barrier mountains, and in the beckoning sea of opalescent sky glimpsed betwixt their summits, was a highly subtle and attenuated matter not to be explained in literal words. Rather was it an affair of vague psychological symbolism and aesthetic association—a thing mixed up with exotic poetry and paintings, and with archaic myths lurking in shunned and forbidden volumes.
Even the wind’s burden held a peculiar strain of conscious malignity; and for a second it seemed that the composite sound included a bizarre musical whistling, or piping over a wide range as the blast swept in and out of the omnipresent and resonant cave mouths. There was a cloudy note of reminiscent repulsion in this sound, as complex and unplaceable as any of the other dark impressions.
We were now, after a slow ascent, at a height of twenty-three thousand five hundred and seventy feet according to the aneroid; and had left the region of clinging snow definitely below us. Up here were only dark, bare rock slopes and the start of rough-ribbed glaciers—but with those provocative cubes, ramparts, and echoing cave mouths to add a portent of the unnatural, the fantastic, and the dreamlike.
Looking along the line of high peaks, I thought I could see the one mentioned by poor Lake, with a rampart exactly on top. It seemed to be half lost in a queer Antarctic haze—such a haze, perhaps, as had been responsible for Lake’s early notion of volcanism.
The pass loomed directly before us, smooth and windswept between its jagged and malignly frowning pylons. Beyond it was a sky fretted with swirling vapors and lighted by the low polar sun—the sky of that mysterious farther realm upon which we felt no human eye had ever gazed.
A few more feet of altitude and we would behold that realm. Danforth and I, unable to speak except in shouts amidst the howling, piping wind that raced through the pass and added to the noise of the unmuffled engines, exchanged eloquent glances. And then, having gained those last few feet, we did indeed stare across the
