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 23,000 or 24,000 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 12,000 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 hoary 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 unfavourable to change, and calculated to retard the usual climatic processes of rock disintegration.
