Plains of Passage (70 page)

In pure water, it is hardly soluble at all, but water that is even slightly acid attacks limestone. During warmer seasons and when climates were humid, circulating ground water, bearing carbonic acid from plants and charged with carbon dioxide, dissolved vast quantities of the carbonate rock.

Flowing along flat bedding planes and down minute cracks at the vertical joints in the thick layers of the calcareous stone, the ground
water gradually widened and deepened the fissures. It carved jagged pavements and intricate grooves as it carried the dissolved limestone away, to escape in seepages and springs. Forced to lower levels by gravity, the acidic water enlarged underground cracks into caves. Caves became caverns and stream channels, with narrow vertical shafts opening into them, and eventually joined with others to become entire subterranean water systems.

The dissolving rock below the ground had a profound effect on the land above it, and the landscape, called karst, displayed unusual and distinctive features. As caves became larger, and their tops extended closer to the surface, they collapsed, creating steep-walled sinkholes. Occasional remnants of the cavern roofs left natural bridges. Streams and rivers running along the surface would suddenly disappear into the sinkholes and flow underground, sometimes leaving valleys that had been formed earlier by rivers, high and dry.

   Water was becoming harder to find. Running water quickly sank into cavities and potholes in the rocks. Even after a heavy rainfall, the water disappeared almost instantly, with no rivulets or streams running across the ground. Once the travelers had to go to a small pool at the bottom of a sinkhole for the precious fluid. Another time, water suddenly appeared in a large spring, flowed across the surface for a while, then disappeared underground again.

The ground was barren and rocky, with thin surface soil that exposed underlying rock. Animal life was scarce as well. Except for some mouflon, with their tightly curled wool coats thickened for winter, and heavy curling horns, the only animals they saw were a few rock marmots. The quick, wily little creatures were adept at evading their many predators. Whether it was wolves, arctic foxes, hawks, or golden eagles, a high-pitched whistle from a lookout sent them scurrying into small holes and caves.

Wolf tried to follow them in pursuit, to no avail, but since long-legged horses were not normally perceived as dangerous, Ayla managed to down a few with her sling. The furry little rodents, fattened for winter hibernation, tasted much like rabbit, but they were small, and for the first time since the previous summer, they often fished the Great Mother River for their dinner.

At first their uneasiness made Ayla and Jondalar very careful traveling through the karst landscape, with its strange formations, caves, and holes, but familiarity lessened their concern. They were walking to give the horses a rest. Jondalar had Racer on a long lead but let him stop to graze a mouthful of the sparse dry grass now and then. Whinney was
doing the same, biting off a mouthful, then following Ayla, though she was not using the halter.

“I wonder if the danger Jeren was trying to warn us about was this barren land full of caves and holes,” Ayla was saying. “I don’t like it much here.”

“No, I don’t either. I didn’t know it would be like this,” Jondalar said.

“Haven’t you been here before? But I thought you came this way,” the woman said, looking surprised. “You said you followed the Great Mother River.”

“We did follow the Great Mother River, but we stayed on the other side. We didn’t cross until we were much farther south. I thought it would be easier to stay on this side coming back, and I was curious about this side. The river makes a very sharp turn not far from here. We were heading east then, and I wondered about the highland that forced her south. I knew this would be the only chance I’d ever have to see it.”

“I wish you had told me before.”

“What difference does it make? We’re still following the river.”

“But I thought you were familiar with this area. You don’t know any more about it than I do.” Ayla wasn’t quite sure why it bothered her so much, except that she had counted on him to know what to expect, and now she found that he didn’t. It made her feel nervous about the strange place.

They had been walking along, involved in the conversation that was edging toward a grievance, if not an argument, and not paying much attention to where they were going. Suddenly Wolf, who had been trotting alongside of Ayla, yipped and nudged her leg. They both turned to look and stopped short. Ayla felt a sudden surge of fright, and Jondalar blanched.

T
he woman and man looked toward the ground ahead and saw nothing. The land in front of them had ceased to be there. They had nearly stepped over the edge of a precipice. Jondalar felt the familiar tightening in his groin as he stared down at the steep drop-off, but he was surprised to see that far below was a long, flat green field, with a stream running through it.

The floors of big sinkholes were usually covered with a deep layer of soil, the insoluble residue of the limestone, and some of the deep sinkholes joined together and opened out into elongated depressions, creating large areas of land deep below the normal surface. With both soil and water, the vegetation below was rich and inviting. The problem was that neither of them could see any way to get down to the green meadow at the bottom of the steep-sided hole.

“Jondalar, there’s something wrong about this place,” Ayla said. “It’s so dry and barren, hardly anything can live up here; down there is a beautiful meadow with a stream and trees, but nothing can reach it. Any animal that tried would die in the fall. It’s all mixed up. It feels wrong.”

“It does feel wrong. And maybe you’re right, Ayla. Maybe this is what Jeren was trying to warn us about. There’s not much here for hunters, and it’s dangerous. I’ve never known of a place where you had to worry about falling over a cliff when you’re just walking across the land.”

Ayla bent down, grabbed Wolf’s head with both her hands, and touched her forehead to his. “Thank you, Wolf, for warning us when we weren’t paying attention,” she said. He whined his affection and licked her face in response.

They backed up and led the the horses around the deep hole, without saying much. Ayla couldn’t even remember what was so important about the argument they almost had. She only thought that they should never have gotten so distracted that they didn’t even see where they were going.

As they continued north, the river on their left began flowing through a gorge that was becoming deeper as the rocky cliffs got higher.
Jondalar wondered whether they should try to follow close to the water or keep to the highland above, but he was glad they were following the river’s course and not attempting to cross it. Rather than valleys with grassy slopes and broad floodplains, in karst regions the large rivers that could be seen from the surface tended to flow in steep-sided limestone gorges. As difficult as it was to use waterways as travel routes with no stream edge to walk along, it was even harder to get across them.

Remembering the great gorge farther south, with long stretches where there were no banks, Jondalar decided to stay on the highland. As they continued to climb, he was relieved to see a long thin stream of water falling down the face of the rock into the water of the river below. Although the waterfall was across the river, it meant some water was available on the higher ground, even though most of it quickly disappeared into the cracks of the karst.

But karst was also a landscape with many caves. They were so frequent that Ayla and Jondalar, and the horses, spent the next two nights protected from the weather by stone walls, without having to put up the tent. After examining several, they began to develop a sense about which openings in the rock were likely to be suitable for them.

Although water-filled caverns deep underground were continuing to increase in size, most enterable caves near the surface were no longer growing larger. Instead, the space inside was decreasing, sometimes rapidly when the general conditions were wet, though hardly changing at all during dry spells. Some caves could only be entered in dry weather; they would fill up during heavy rains. Some, though always open, had running streams covering the floors. The travelers looked for dry caves, usually somewhat higher up, but water, along with limestone, had been the instrument that had shaped and sculpted all of them.

Rainwater, slowly seeping through the rock of the roof, absorbed the dissolved limestone. Each drip of calcareous water, even the tiniest droplet of moisture in the air, was saturated with calcium carbonate in solution, which was redeposited inside the cave. Though usually pure white, the hardened mineral could be beautifully translucent, or mottled and shaded with gray, or faintly colored with tints of red or yellow. Pavements of travertine were created, and immovable draperies festooned the walls. Icicles of stone hanging from the ceiling strained with each wet drop to meet their counterparts growing slowly from the floor. Some were joined in thin-waisted columns, which grew thicker with time in the ever-changing cycle of the living earth.

   The days were getting noticeably colder and windier, and Ayla and Jondalar were glad for the prevalence of caves to break the chill of the
wind. They usually checked potential shelters to make sure they were not occupied by four-legged inhabitants before they moved in, but they found they could rely on the keener senses of their traveling companions to warn them of danger. Without saying so, or consciously considering it, they depended on the smell of smoke to tell them if there were human occupants—humans were the only animals that used fire—but they encountered no one, and even other animal species were rare.

Therefore, they were surprised when they came to a region that was unusually lavish in vegetation, at least compared with the rest of the barren, rocky landscape. Limestone was not all the same. It varied greatly in how easily it dissolved, and in the proportion that was insoluble. As a result, some areas of limestone karst were fertile, with meadows and trees growing beside normal streams that flowed on the surface. Sinking lands and caves and underground rivers did exist in those areas, but they were rarer.

When they came upon a herd of reindeer grazing in a field of dry standing hay, Jondalar looked at Ayla with a smile, then pulled out his spear-thrower. Ayla nodded in agreement and urged Whinney to follow the man and the stallion. With nothing around but a few small animals, hunting had been poor, and as the river was by then far below in the gorge, they hadn’t been able to fish. They had been subsisting essentially on dried food and emergency traveling rations, even sharing some with the wolf. The horses were hard pressed, too. The scraggly grass that managed to grow in the thin soil had been barely sufficient for them.

Jondalar slit the throat to bleed the small-antlered doe they killed. Then they lifted the carcass into the bowl boat attached to the travois and looked for a place to camp nearby. Ayla wanted to dry some of the meat and render the animal’s winter fat, and Jondalar was looking forward to a good piece of roast haunch and some tender liver. They thought they’d stay a day or so, especially with the meadow nearby. The horses needed the feed. Wolf had discovered an abundance of small creatures, voles, lemmings, and pikas, and had gone off to hunt and explore.

When they noticed a cave tucked into a hillside, they headed for it. It was a little smaller than they would have liked, but it seemed sufficient. They dropped the pole drag and unloaded the horses to let them enjoy the meadow, put the packs beside the cave, and dragged the travois over themselves, then spread out to collect woody brush and dried dung.

Ayla was looking forward to making a meal with fresh meat and was thinking about what to cook with it. She gathered some dried seed heads and grains from the meadow grasses, and handfuls of the tiny black seeds from the pigweed that was growing beside a small stream
somewhat north of the cave. When she returned, Jondalar had already started the fire, and she asked him to go to the stream and fill up the waterbags.

Wolf arrived before the man came back, but when the animal approached the cave, he bared his teeth and snarled menacingly. Ayla felt the hairs on the back of her neck rise.

“Wolf, what is it?” she said, unconsciously reaching for her sling and picking up a stone, although her spear-thrower was just as close. The wolf stalked slowly into the cave, his throat rumbling with a deep snarl. Ayla followed behind, ducking her head to enter the small dark opening in the rock, and she wished she had brought a torch. But her nose told her what her eyes could not see. It had been many years since she had smelled that odor, but she would never forget it. Suddenly her mind pictured that first time so long ago.

   They were in the foothills of the mountains not far from the Clan Gathering. Her son was riding on her hip, supported by his carrying cloak, and though she was young and one of the Others, she was walking in the medicine woman’s position. They had all stopped in their tracks and were staring at the monstrous cave bear, nonchalantly scratching his back against the bark of the tree.

Though the huge creature, twice the size of ordinary brown bears, was the most revered totem of all the Clan, the young people of Brun’s clan had never seen a living one. There were none left in the mountains near their cave, though dry bones attested to the fact that there once had been. For the powerful magic they contained, Creb had retrieved the few tufts of hair that had been caught in the bark after the cave bear finally lumbered off, leaving only his distinctive smell behind.

   Ayla signaled Wolf and backed out of the cave. She noticed the sling in her hand and tucked it in her waist tie with a wry face. What good was a sling against a cave bear? She was just grateful that the bear had begun his long sleep and hadn’t been disturbed by her intrusion. She quickly threw dirt on the fire and stamped it out, then picked up her pack-saddle basket and moved it away from the cave. Fortunately they hadn’t unpacked very much. She went back for Jondalar’s pack and then dragged the travois by herself. She had just picked up her pack again to move it farther away when Jondalar appeared with the full waterbags.
