feet. She felt light enough to lift off and float free of the earth. Then she began to dance to the drums, her bare feet shuffling in the dust, eyes burning from the potion and the shifting pall of smoke.
After she had made a number of slow circuits around the firepit, the shaman led her to the domed rock that jutted from the lip of their ledge like a bowsprit.
Corn Blossom climbed to the crest of the rock and looked back at her mother, her sisters, brothers, aunts, uncles and grandparents. Their drumming and chanting was mixed with sobbing and shrill cries. She loved them, and she loved the world as she remembered it, before the rain stopped falling. For the return of that happy time, no sacrifice was too great. She turned away from the familiar faces, her heart aching.
Arms spread wide, Corn Blossom closed her eyes and jumped into the dark.
The shaman had promised her no pain.
He was almost right.
The wind whipping past her ears drowned out the drumbeats and the screams of sorrow. When her head hit the sloping cliff some fifty feet down, there was an instant of sharp discomfort, then her unconscious body started to tumble and bounce. She never felt the impact with the canyon floor.
At daybreak when her people climbed down, they found no body. The only footprints in the sand were theirs.
SOME SEVEN HUNDRED YEARS later, in the spring of 1992, a Korean war-surplus 6x6 stopped on the same canyon floor. The river flowed cloudy and green in a deep channel along the foot of Corn Blossom’s cliff. Among the ten tourists sitting in the bench seats on the truck bed was a stocky black woman in her late twenties. She aimed her 35 mm camera at the high cleft. The telephoto zoom lens revealed a double row of deserted structures partially hidden in shadow.
A thirteenth century high-rise, Dr. Mildred Wyeth thought, snapping the shutter. She wished she could have seen the view from up there. But that was impossible because the archaeological site, like the others in the canyon, was off-limits to nonmembers of the Hopi tribe, who owned the land.
Other shutters clicked around her, like spastic castanets.
With the long lens Mildred picked out the hand- and footholds chipped into the nearly vertical bedrock—the commute to and from the canyon bottom had been perilous, to say the least.
The canyon’s vanished residents had been a vigorous, athletic people with no fear of heights. A stark contrast to Mildred’s fellow passengers, who preferred to have their life experiences spoon-fed to them while sitting down. Her companions for the day included four Japanese men in Bermuda shorts; an impatient German couple who had brought along enough food for six, but had offered to share none of it; and three portly, middle-aged American ladies in brand-new, pastel bill-caps, T-shirts, daypacks and hiking shoes.
Mildred would’ve much rather explored the canyon on foot or horseback, but the constraints of a week-long holiday and a lengthy itinerary made that impossible. It was her first real vacation in a long time, and she had crammed it full of interesting things to do. Perhaps too full, it turned out.
Though Mildred was a medical doctor, she didn’t have a client practice. She worked for a university-affiliated, cryogenic research company. Her field of expertise was cellular crystallization, one of the major obstacles to successful reanimation of living tissue from deep cold.
The basic problem was biophysical. When the cells of most animals were frozen, their watery fluids turned to ice, which expanded to burst or crush vital, cellular components. Only a handful of species had cells that could withstand freezing, and those species revived on their own when warmed. The cells of these unique creatures contained a sugar called trehalose, which acted like antifreeze, lowering the crystallization temperature. Mildred had already verified that the transplant life of dissected, refrigerated rat hearts could be extended by many days when stored in a trehalose solution. Her ongoing research tested ways the sugar could be introduce into living bodies, and the effects of different concentrations during freezing.
Mildred was passionate about her work, which she believed would ultimately change the way all human disease was fought. Once the cryogenic process was perfected, dying patients could be safely stored until science found cures, however long that took.
While Mildred and the others snapped photos of the ruins, the sour-faced Hopi driver-tour guide probed his ear with a wooden matchstick. He wore a straw cowboy hat and his gray-streaked black hair was pulled back in a long ponytail. No cab separated him from his passengers; the 6x6 had a floorplan like a bus, only without a roof or side walls to obstruct the views.
When the shutter-clicking slowed, the driver tucked the grooming tool back in his hat band and spoke into a hand microphone. His slow drawl came out of a loudspeaker screwed to the truck bed’s wooden rails. “That settlement’s number eleven on your list,” he informed them. “We call it the Castle because it’s so high up, and because folks think it looks like one. It was first excavated in 1928, by archaeologists from the University of California at Berkeley. The buildings are from the Pueblo Three Period, from 1050 to 1300 A.D. Our ancient ones lived up there for more than five hundred years.”
By “our,” he meant Hopi.
From her advance reading on the subject, Mildred knew there were few hard facts about the cliff people of the canyon. They had drawn symbols on the rocks, but had left no written language to explain them. It was assumed that extended drought, which the area was prone to, had driven them away. Where they had gone and what had happened to them was anybody’s guess. The Navajo, who had lived nearby for millennia, referred to the cliff people as “our ancient enemies.” The Hopi and Navajo had been enemies for as long as anyone could remember, so the Hopi concluded they were related to the cliff people.
Mildred tuned out her guide. Aside from parroting terms and theories devised by social scientists to fill doctoral theses, he had nothing new to say about the missing residents, or their erased culture. Looking up at the abandoned site, Mildred felt a profound sense of loss, and of tragedy. Looking up at the ruins, she was certain that what had happened to the cliff people could never happen to her own, immensely more powerful civilization. Mildred believed in human progress and the perfectability of knowledge, a juggernaut of scientific truth rolling ever forward, ever faster.
She was dead wrong on all counts, of course.
Numbers alone didn’t guarantee immunity from extinction. Nor did the weight of accumulated scientific knowledge. A century would pass before she saw the awful truth with her own eyes: That a juggernaut of progress could fly apart in an instant and take everything with it.
The final site on the tour was a half mile down-canyon, on the other side of a freestanding spire almost as tall as the mesa. Shutters snapped, but feebly this time; the pile of rocks on a low slope was hardly scenic.
“Those are the ruins of an old cabin, number twelve on your list,” the guide said. “The woman who lived in it spent her whole life in this canyon. She was born here. She never married. She died in that hut at age 109 in the 1930s. People believe she was the last of a long, unbroken line of powerful witches. They say she spoke with the spirits of our ancient ones, and that while she was alive her magic spells kept the canyon’s demons sleeping. Some folks say they still do.”
Mildred perked up. There was very little in the academic literature about the spiritual beliefs, or supposed beliefs, of the canyon’s lost people.
“What demons?” she asked him.
“Man-eaters,” he said matter-of-factly. “Folks say they’ve always been here. No one’s sure whether the drought makes
