She took a deep breath and willed herself to continue packing the basket. She put the fire-making materials and aurochs horn into it, then took several flint tools out of the folds of her wrap. From another fold she took a round pebble, tossed it in the air, and caught it again. Any stone of the right size could be hurled with a sling, but accuracy was better with smooth round missiles. She kept the few she had.
Then she reached for her sling, a deerskin strap with a bulge in the middle for holding stones, and long tapered ends twisted from use. No question about keeping it. She untied a long lace of leather that was wound around her soft chamois-skin wrap in such a way as to create the folds in which she carried things. The wrap came off. She stood naked except for the small leather pouch fastened to a cord around her neck—her amulet. She slipped it over her head and shivered, feeling more naked without her amulet than she did without her wrap, but the small hard objects within it were reassuring.
That was it, the sum total of her possessions, all she needed to survive—that and knowledge, skill, experience, intelligence, determination, and courage.
Quickly, she rolled up her amulet, tools, and sling in her wrap and put them in the basket, then wrapped the bearskin around it and tied it with the long thong. She enfolded the bundle with the aurochs-hide tent and tied it behind the fork of the log with the vine.
She stared at the wide river and the far shore for a while, and thought of her totem, then kicked sand on the fire and shoved the log with all her precious possessions into the river downstream of the entangling tree. Lodging herself at the forked end, Ayla grabbed the protruding stubs of former branches and launched her raft with a push.
Still chilled by melt from the glacier, the icy water enveloped her naked body. She gasped, hardly able to breathe, but a numbness set in as she became inured to her frigid element. The powerful current grabbed the log, trying to finish its job of transporting it to the sea, and tossed it between swells, but the forked branches kept it from rolling. Kicking hard, she struggled to force her way across the surging flow, and veered at an angle toward the opposite shore.
But progress was agonizingly slow. Every time she looked, the other side of the river was farther than she expected. She was moving much faster downstream than across. By the time the river swept her past the place she had thought to land, she was tired, and the cold was lowering her body temperature. She was shivering. Her muscles ached. It felt as though she had been kicking forever with rocks tied to her feet, but she forced herself to keep on.
Finally, exhausted, she surrendered to the inexorable force of the tide. The river, taking its advantage, swept the makeshift raft back in the direction of the stream, with Ayla clinging on desperately as the log now controlled her.
But ahead, the river’s course was changing, its southerly direction swerving sharply west as it curved around a jutting spit of land. Ayla had traversed more than three-quarters of the way across the racing torrent before giving in to her fatigue, and when she saw the rocky shore, with a resolute effort, she took control.
She forced her legs to kick, pushing to reach the land before the river carried her around the point. Closing her eyes, she concentrated on keeping her legs moving. Suddenly, with a jolt, she felt the log grate against the bottom and come to a stop.
Ayla couldn’t move. Half submerged, she lay in the water still clinging to the branch stubs. A swell in the turbulent stream lifted the log free of the sharp rocks, filling the young woman with panic. She forced herself to her knees and shoved the battered tree trunk forward, anchoring it to the beach, then fell back into the water.
But she couldn’t rest long. Shivering violently in the cold water, she made herself crawl onto the rocky spit. She fumbled with the knots in the vine, and, with that loosened, she hauled the bundle to the beach. The thong was even more difficult to untie with her trembling fingers.
Providence helped. The thong broke at a weak spot. She clawed the long leather strap away, pushed the basket aside, and crawled on the bearskin and wrapped it around her. By the time her shivering stopped, the young woman was asleep.
Ayla headed north and slightly west after her perilous river crossing. The summer days warmed as she searched the open steppeland for some sign of humanity. The herbal blossoms that had brightened the brief spring faded, and the grass neared waist high.
She added alfalfa and clover to her diet, and welcomed the starchy, slightly sweet groundnuts, finding the roots by tracing rambling surface vines. Milk-vetch pods were swelling with rows of oval green vegetables in addition to edible roots, and she had no trouble distinguishing between them and their poisonous cousins. When the season for the buds of day lilies passed, the roots were still tender. A few early-ripening varieties of low-crawling currants had begun to turn color, and there were always a few new leaves of pigweed, mustard, or nettles for greens.
Her sling did not lack for targets. Steppe pikas, souslik marmots, great jerboas, varying hares—gray brown now instead of winter white—and an occasional, omnivorous, mouse-hunting giant hamster abounded on the plains. Low-flying willow grouse and ptarmigan were a special treat, though Ayla could never eat ptarmigan without remembering that the fat birds with the feathered feet had always been Creb’s favorite.
But those were only the smaller creatures feasting on the plain’s summer bounty. She saw herds of deer—reindeer, red deer, and enormous antlered giant deer; compact steppe horses, asses, and onagers, which resembled both; huge bison or a family of saiga antelope occasionally crossed her path. The herd of reddish brown wild cattle, with bulls six feet at the withers, had spring calves nursing at the ample udders of cows. Ayla’s mouth watered for the taste of milk-fed veal, but her sling was not an adequate weapon to hunt aurochs. She glimpsed migrating woolly mammoths, saw musk oxen in a phalanx with their young at their backs facing down a pack of wolves, and carefully avoided a family of evil-tempered woolly rhinoceroses. Broud’s totem, she recalled, and suitable, too.
As she continued northward, the young woman began to notice a change in the terrain. It was becoming drier and more desolate. She had reached the ill-defined northern limit of the wet, snowy continental steppes. Beyond, all the way to the sheer walls of the immense northern glacier, lay the arid loess steppes, an environment that existed only when glaciers were on the land, during the Ice Age.
Glaciers, massive frozen sheets of ice that spanned the continent, mantled the Northern Hemisphere. Nearly a quarter of the earth’s surface was buried under their unmeasurable crushing tons. The water locked within their confines caused the level of the oceans to drop, extending the coastlines and changing the shape of the land. No portion of the globe was exempt from their influence, rains flooded equatorial regions and deserts shrunk, but near the borders of the ice the effect was profound.
The vast ice field chilled the air above it, causing moisture in the atmosphere to condense and fall as snow. But nearer the center high pressure stabilized, creating extreme dry cold and pushing the snowfall out toward the edges. The huge glaciers grew at their margins; the ice was nearly uniform across its full sweeping dimensions, a sheet of ice more than a mile thick.
With most of the snow falling on the ice and nourishing the glacier, the land just south of it was dry—and frozen. The constant high pressure over the center caused an atmospheric chute funneling the cold dry air toward lower pressures; wind, blowing from the north, never stopped on the steppes. It only varied in intensity. Along the way it picked up rock that had been pulverized to flour at the shifting border of the grinding glacier. The airborne particles were sifted to a texture only slightly coarser than clay—loess—and deposited over hundreds of miles to depths of many feet, and became soil.
In winter, howling winds whipped the scant snowfall across the bleak frozen land. But the earth still spun on its tilted axis, and seasons still changed. Average yearly temperatures only a few degrees lower trigger the formation of a glacier; a few hot days have little effect if they don’t alter the average.
In spring the meager snow that fell on the land melted, and the crust of the glacier warmed, seeping down and out across the steppes. The meltwater softened the soil enough, above the permafrost, for shallow rooting grasses and herbs to sprout. The grass grew rapidly, knowing in the heart of its seed that life would be short. By the middle of summer, it was dry standing hay, an entire continent of grassland, with scattered pockets of boreal forest and tundra nearer the oceans.
In the regions near the borders of the ice, where the snow cover was light, the grass supplied fodder the year around for uncountable millions of grazing and seed-eating animals who had adapted to the glacial cold—and to predators who can adapt to any climate that supports their prey. A mammoth could graze at the foot of a gleaming, blue-white wall of ice soaring a mile or more above it.
The seasonal streams and rivers fed by glacial melt cut through the deep loess, and often through the sedimentary rock to the crystalline granite platform underlying the continent. Steep ravines and river gorges were common in the open landscape, but rivers provided moisture and gorges shelter from the wind. Even in the arid loess steppes, green valleys existed.
The season warmed, and, as one day followed the next, Ayla grew tired of traveling, tired of the monotony of the steppes, tired of the unrelenting sun and incessant wind. Her skin roughened, cracked, and peeled. Her lips were chapped, her eyes sore, her throat always full of grit. She came across an occasional river valley, greener and more wooded than the steppes, but none tempted her to stay, and all were empty of human life.
Though skies were usually clear, her fruitless search cast a shadow of fear and worry. Winter alwa
ys ruled the land. On the hottest day of summer, the harsh glacial cold was never far from thought. Food had to be stockpiled and protection found to survive the long bitter season. She had been wandering since early spring and was beginning to wonder if she were doomed to roam the steppes forever—or die after all.
She made a dry camp at the end of another day that was so like the days that had gone before it. She had made a kill, but her coal was dead, and wood was getting more scarce. She ate a few bites raw rather than bothering with a fire, but she had no appetite. She threw the marmot aside, although game seemed more scarce too—or she wasn’t keeping as sharp an eye out for it. Gathering was more difficult as well. The ground was hard-packed and matted with old growth. And there was always the wind.
She slept poorly, troubled by bad dreams, and awoke unrested. She had nothing to eat; even her discarded marmot was gone. She took a drink—stale and flat—packed her carrying basket, and started north.
