The hazards of winter travel in the North are manifold at best, but the country which Emerson and his companions had to traverse was particularly perilous, owing to the fact that their course led them over the backbone of the great Alaskan Range, that desolate, skyscraping rampart which interposes itself between the hate of the Arctic seas and the tossing wilderness of the North Pacific. This range forms a giant, ice-armored tusk thrust out to the westward and curved like the horn of an African rhino, its tip pointed eight hundred miles toward the Asiatic coast, its soaring peaks veiled in perpetual mist and volcanic fumes, its slopes agleam with lonely ice-fields. It is a saw-toothed ridge, for the most part narrow, unbroken, and cruel, and the rival winter gales roar over it in a never-ceasing war. On the north lies the Forgotten Land, to the south are the tempered reaches of the Pacific. In summer the stern sweep of rock and tundra is soaked with weeping rains, and given over to the herding caribou or the great grass-eating bear; but when from the polar regions the white hand of winter stretches forth, the grieving seas lift themselves, the rain turns to bitter, hail-burdened hurricanes that charge and retreat in a death-dealing conflict, sheathing the barrier anew, and confounding the hearts of men on land and sea. The coast is unlighted and badly mapped, hence the shore is a graveyard for ships, while through the guts, which at intervals penetrate the range, the blizzards screech until travellers burrow into drifts to avoid their fury or lie out in stiff sleeping-bags exposed to their anger. It is a region of sudden storms, a battle-ground of the elements, which have swept it naked of cover in ages past, and it is peopled scantily by handfuls of coughing natives, whose igloos are hidden in hollows or chained to the ground with cables and ship's gear. It was thither the travellers were bound, headed toward Katmai Pass, which is no more than a gap between peaks, through which the hibernal gales suck and swirl. This pass is even balder than the surrounding barrens, for it forms a funnel at each end, confining the winds and affording them freer course. Notwithstanding the fact that it had an appalling death-list and was religiously shunned, Emerson would hearken to no argument for a safer route, insisting that they could spare no time for detours. Nothing dampened his spirits, no hardship daunted him; he was tireless, ferocious in his haste. A week of hard travel found them camped in the last fringe of cottonwood that fronted the glacial slopes, their number augmented now by a native from a Russian village with an unpronounceable name, who, at the price of an extortionate bribe, had agreed to pilot them through. For three days they lay idle, the taut walls of their tent thrumming to an incessant fusillade of ice particles that whirled down ahead of the blast, while Emerson fumed to be gone.
