If the sculptured maps and pictures in that prehuman city had told truly

If the sculptured maps and pictures in that prehuman city had told truly, these cryptic violet mountains could not be much less than three hundred miles away; yet none the less sharply did their dim elfin essence appear above that remote and snowy rim, like the serrated edge of a monstrous alien planet about to rise into unaccustomed heavens. Their height, then, must have been tremendous beyond all comparison — carrying them up into tenuous atmospheric strata peopled only by such gaseous wraiths as rash flyers have barely lived to whisper of after unexplainable falls. Looking at them, I thought nervously of certain sculptured hints of what the great bygone river had washed down into the city from their accursed slopes — and wondered how much sense and how much folly had lain in the fears of those Old Ones who carved them so reticently. I recalled how their northerly end must come near the coast at Queen Mary Land, where even at that moment Sir Douglas Mawson’s expedition was doubtless working less than a thousand miles away; and hoped that no evil fate would give Sir Douglas and his men a glimpse of what might lie beyond the protecting coastal range. Such thoughts formed a measure of my overwrought condition at the time — and Danforth seemed to be even worse.
Yet long before we had passed the great star-shaped ruin and reached our plane, our fears had become transferred to the lesser but vast-enough range whose recrossing lay ahead of us. From these foothills the black, ruin-crusted slopes reared up starkly and hideously against the east, again reminding us of those strange Asian paintings of Nicholas Roerich; and when we thought of the frightful amorphous entities that might have pushed their fetidly squirming way even to the topmost hollow pinnacles, we could not face without panic the prospect of again sailing by those suggestive skyward cave mouths where the wind made sounds like an evil musical piping over a wide range. To make matters worse, we saw distinct traces of local mist around several of the summits — as poor Lake must have done when he made that early mistake about volcanism — and thought shiveringly of that kindred mist from which we had just escaped; of that, and of the blasphemous, horror-fostering abyss whence all such vapors came.
All was well with the plane, and we clumsily hauled on our heavy flying furs. Danforth got the engine started without trouble, and we made a very smooth take-off over the nightmare city. Below us the primal Cyclopean masonry spread out as it had done when first we saw it, and we began rising and turning to test the wind for our crossing through the pass. At a very high level there must have been great disturbance, since the ice-dust clouds of the zenith were doing all sorts of fantastic things; but at twenty-four thousand feet, the height we needed for the pass, we found navigation quite practicable. As we drew close to the jutting peaks the wind’s strange piping again became manifest, and I could see Danforth’s hands trembling at the controls. Rank amateur that I was, I thought at that moment that I might be a better navigator than he in effecting the dangerous crossing between pinnacles; and when I made motions to change seats and take over his duties he did not protest. I tried to keep all my skill and self-possession about me, and stared at the sector of reddish farther sky betwixt the walls of the pass — resolutely refusing to pay attention to the puffs of mountain-top vapor, and wishing that I had wax-stopped ears like Ulysses’ men off the Siren’s coast to keep that disturbing windpiping from my consciousness.
