Again in his mind’s eye he saw a world out of balance. Sixteen years ago, it had seemed a small, harmless thing indeed. Ignore it, everyone had said. If these were to be the consequence of that action, they were terrible consequences indeed.
He reached the edge of the benchland. Below, in the floodplain, he could see the expedition’s horses. They had stopped grazing now and were standing alert, their ears pricked up, staring upstream. But it was already too late to save them. To ride down into the floodplain now would be suicide. He shouted and waved his hat; but his voice did not carry above the growing roar, and the herd’s attention was elsewhere.
The ground trembled. As the noise continued to intensify, Beiyoodzin became unable to separate the terrified whinnies of his own horse from the scream of the coming water. He looked upstream, into the maw of an even stronger wind that thrashed at the salt cedars and pressed the willows almost horizontal to the ground.
Then he saw it come around the bend: a vertical wall twenty feet high, moving with the speed of a freight train, driving the howling wind before it.
But it was not a wall of water. Instead, Beiyoodzin beheld a seething rampart of tree trunks, roots, boulders, and boiling dirt; a huge churning mass, pushed ahead by the flood at eighty miles an hour. He struggled to control his horse.
The horses below wheeled in hopeless fright and ran. As Beiyoodzin watched—in a mixture of amazement, horror, and fearful reverence—the monstrous wall bore down on them relentlessly. In rapid succession the animals were struck and blown apart, turned inside out like the abrupt blossoming of a rose, the ropy eruptions of scarlet, chunks of meat, and shattered legs disappearing into the roiling mass of logs and boulders.
Piled behind the murderous wall of debris came the great engine of its momentum: a tidal wave of chocolate-colored water two hundred yards wide, boiling from benchland to benchland in a flow that for the moment was greater than the Colorado River itself. It blasted a path through the valley, leaping into haystacks of water and standing waves ten feet high. The flood ripped at the edges of the plain like a chainsaw, tearing out hundred-ton chunks of earth and sucking away cottonwood trees. At the same time, Beiyoodzin felt a wave of intense humidity pass over him. The air grew suddenly pregnant with the rich scent of wet earth and lacerated vegetation. Despite his distance, he instinctively backed up his horse as the walls of the benchland began caving in before him.
From still higher ground, he stared down at the humped and gnarled backside of the tidal wave as it thundered down the valley toward the dark slot canyon in the far rock face. As the flood struck the opening of the slot, he felt the brutal crash ripple beneath his feet. An enormous shockwave shuddered backward through the torrent, momentarily stopping the forward motion of the flood, atomizing the water. A vast curtain of brown spume erupted along the rock face, rising several hundred feet up the cliffs with terrifying speed before gradually falling back.
Now the torrent settled into a new pattern. The floodwaters continued to pile up against the slot canyon, forcing their way in, creating an instant lake: a huge, angry maelstrom of water boiling at the canyon’s mouth. Man-sized splinters of wood were thrown from the water as the swirling trees were torn apart by the violent pressure.
Another huge piece of benchland caved in before him. Shaking, Beiyoodzin turned his horse from the appalling scene and headed in the direction of the old Priest’s Traiclass="underline" the back door into the valley of Quivira. It had been too late to save the horses. And now he wondered if anyone—including himself—would get out of Chilbah Valley alive.

WITH THE HELP OF ARAGON AND SMITHBACK, Nora tied off the ripped covering around Holroyd’s body bag and lashed it to the pole. Then she stood back, wiping her brow with the back of her hand. Although she knew it had to be done, she was reluctant to begin the awkward, arduous, depressing task of lugging Holroyd’s body, along with several drysacks full of gear, out to where the packhorses waited.
She looked up, scanning the canyon ahead. On the far side of the pool and well above her head was the massive cottonwood trunk. Beyond was a steep climb to the next pool; it was going to be hell, she knew, to get across it. The rising wind blew a strand of hair across her face, which she unconsciously tucked back behind her ear. She took a deep breath, knelt, and grasped one end of the pole.
Then she froze. There was another breath of wind on her cheek, stronger this time. Along with it came the sudden, strangely pleasant scent of crushed vegetation.
Fear sent blood surging in her ears. The wind was accelerating with an almost machinelike precision, very different from a natural, intermittent breeze. Even as she paused it became stronger.
“Flash flood,” she said.
“Yeah?” The sky overhead was calm and blue; Smithback’s tone was curious, not worried. “How can you tell?”
But Nora didn’t hear him. Her mind was calculating furiously. They were at least a quarter mile into the slot canyon. There was no way to get out in time. Their only chance was to climb, to get above the level of the flood.
Quickly, she pointed up toward the cavity in the rock where Holroyd’s corpse had been stored. “Drop the body,” she said urgently, “drop everything. Let’s go!”
Smithback began to protest. “We can’t just—”
“Move!” Aragon said urgently, releasing the other end of the pole. The body slid into the pool, turning lazily. Nora began thrashing through the water downstream, toward the spot where the ledge angled upward to the small cave.
“Where are you going?” Smithback called, disbelief strong in his voice. “Shouldn’t we be heading the other way?”
“No time!” she cried. “Come on, hurry! Hurry!”
Beneath the driving wind, Nora could now hear a faint noise: a low-frequency sound, deep and menacing. The calm pools of water in the stream broke into a dancing chop. The hastily abandoned drysacks began to bob and roll wildly.
She floundered across the pool, breath coming in sobs. The wind grew, and grew, and then there was a painful pop in her ears: a drastic change in air pressure. She looked back at Smithback and Aragon, wet and bedraggled, and tried to scream at them to hurry. Her voice was drowned by a vast, distorted roar that washed through the slot canyon, popping her ears a second time.
In its wake came an intense silence. The wind had suddenly dropped.
She hesitated, confused, her ears straining to catch every nuance of sound. From what seemed to be a vast distance, she could make out clatterings and crunchings, strangely distinct despite their remoteness. She whirled toward the ledge again, realizing she was hearing the sound of boulders and logs jamming into the stone slot, ricocheting off the narrow canyon walls on their way toward them. As she ran, a fresh wind rose to a screaming pitch, tearing shreds of water from the surface of the stream. The flood, she knew, would first turn the slot canyon into a wind tunnel.
She thrashed forward. The sound in the canyon grew to a terrible howl, and the ever-rising hurricane of wind tore at their backs. We’re not going to make it, Nora thought. She glanced back and saw that Aragon had fallen behind. She held out her hands to him, urging him on, screaming words that had no sound over the blast.
Suddenly a boulder came down the canyon from behind them, bounding between the rock walls with thunderous booms, roaring over their heads with horrifying speed. Another, even larger, followed in its wake, propelled ahead of the water by a stochastic amplification of momentum. It hit the jammed cottonwood trunk with a shattering force and continued downcanyon, leaving behind the smell of smoke and crushed stone.
