THE SHELTERS OF STONE

The walls, glinting with crystallized calcite, were nearly white, a pure, clean, resplendent surface. As she moved slowly into the cave, the light from the flickering torch sent animated shadows of the natural relief chasing each other over the walls as though they were alive and breathing. She walked closer to the white walls, which started a little below her chin-about five feet up from ground level-with a rounded ledge of brownish stone, and extended up in a curve that arced inward to the roof. She would not have thought of it before her visit to the deep cave of Fountain Rocks, but she could imagine what an artist like Jonokol might do in a cave like this.

Ayla walked around the room next to the wall, very carefully. The floor was muddy and uneven, and slippery. At the bottom of the U, where it curved around there was a narrow entrance to another gallery. She held the torch up and looked inside. The upper walls were white and curved, but the lower area was a narrow twisting corridor and she decided not to enter. She continued around, and to the right of the entrance to the gallery at the back there was another passageway, but she only looked inside. She had already decided that she would have to tell Jondalar and some others and bring them back to this cave.

Ayla had seen many caves, most filled with beautiful stone icicles suspended from ceilings or stalactite draperies hanging down the walls and corresponding deposits of stalagmites growing to meet them from the floors, but she had never seen a cave like this. Although it was a limestone cave, a layer of impermeable marl had formed that blocked the calcium carbonate-saturated drops of water and kept them from seeping through to form stalactites and stalagmites. Instead the walls were covered with calcite crystals, which grow very little, leaving large panels of white covering the bumps and dips of the natural relief of the stone. It was a rare and beautiful place, the most beautiful cave she had ever seen.

She noticed the light of her torch dimming. It was building up an accumulation of charcoal near the end, stifling the flame. In most caves she would have simply knocked it against any wall to dislodge the burned wood and refresh the fire, but that usually left a black mark. In this place she felt constrained to be careful; she couldn't just knock off the charcoal and mar the unblemished white walls. She chose a place in the darker stone area, lower down. Some of the charcoal dropped on the ground when she rapped the torch against the stone, and she had a momentary urge to clean it up. There was a sacred quality to this place; it felt spiritual, otherworldly, and she didn't want to desecrate it in any way.

Then she shook her head. It's only a cave, she thought, even if it is special. A little charcoal on the ground won't hurt it. Besides, she noticed that the wolf didn't hesitate to mark the place. He had lifted his leg every few feet, proclaiming with his scent that this was his territory. But his scent marks didn't reach the white walls.

Ayla walked back to the camp of the Ninth Cave as quickly as she could, excited to tell people about the cave. It was only when she arrived, and noticed several people were hauling away dirt from a pit oven that had just been dug and several others were preparing food to go into it, that she remembered she had invited some people over the following morning. She had planned to forage for food to cook, to find an animal to hunt or some edible plant food, and in her excitement over the cave she had forgotten all about it. She noticed that Marthona, Folara, and Proleva had taken out an entire haunch of a bison from the cold storage pit.

The first day they arrived, most of the Ninth Cave had worked to dig the large pit all the way down to the level of the permafrost to preserve the part of the meat, which they had hunted before they left, that had not been dried. The land of the Zelandonii was close enough to the northern glacier for permafrost conditions to prevail, but that did not mean the ground was permanently frozen year-round. In winter the soil became as hard as ice, frozen solid all the way to the surface, but in summer a layer on top thawed to varying depths from a few inches to several feet depending on the surface cover and the amount of sun or shade it received. Storing meat in a hole that was dug down to the frost kept it fresh longer, though most people didn't mind if meat aged a little, and some people preferred the flavor of meat that was quite high.

"Marthona, I'm sorry," Ayla said when she reached the main hearth. "I went to find more food for tomorrow's morning meal, but I found a cave nearby and forgot all about it. It is the most beautiful cave I've ever seen, and I wanted to show it to you, and everyone."

"I never heard of any caves nearby," Folara said. "Certainly not any beautiful ones. How far is it?"

"It's just down the other side of that slope at the back of the main camp," Ayla explained.
