<passage>:
It has happened a hundred times in the long history of Earth—and, sooner or later, will happen again! so much as a landslide to bring the Fault to the attention of the general public. anything is news in late August. And the geologists became interested. Seismologists were reporting unusual activity in the area, tremors too severe to be rock slides. Volcanic activity? Specifically, a dust volcano? Unusual, they knew, but right on the Kiowa Fault—could be. Labor Day crowds read the scientific conjectures with late summer lassitude. Sunday supplements ran four-color artists' conceptions of the possible volcano. "Only Active Volcano in U. S.?" demanded the headlines, and some papers even left off the question mark. It may seem odd that the simplest explanation was practically not of the Monday newspapers (page 27 of the New York Times ). The idea was not nearly so exciting as a volcano, even a lava-less one, and you couldn't draw a very dramatic picture of it. California, which almost daily bounced San Francisco or Los Angeles, or some place in between. The dust volcano was on the face of it a more plausible theory. Still, it was only a theory. It had to be proved. As the tremors grew They found, of course, that Schwartzberg had been perfectly correct. They found themselves on the scene of what was fast becoming the most violent and widespread earthquake North America—probably the world—has ever seen in historic times. To describe it in the simplest rolled about like pebbles as they shivered and cracked into pebbles themselves. "It looks like sand dancing in a child's sieve," said the normally impassive Schwartzberg in a nationwide broadcast from the scene of disaster. "No one here has ever seen anything like it." And the landslip was growing, north and south along the Fault. "Get out while you can," Schwartzberg urged the population of the affected area. "When it's over you can come back and pick up the pieces." But the band of scientists who had rallied to his leadership backing north into the deepening trough. At the rate things were going, there might be a new lake the entire length of El Paso and Pueblo Counties. And, warned Schwartzberg, this might only be the beginning. miles away, the now-familiar lurch and steady fall had already sent several thousand Coloradans scurrying for safety. the danger of rock slides from minor quakes. The geologists went home to wait. There wasn't much to wait for. The news got worse and worse. The Platte confusion. Prairie and hill cracked open under intolerable strains as the land shuddered downward in gasps and leaps. Springs burst to the just like that, on the afternoon of 4 October. "We must remain calm," declared the Governor of Nebraska. "We must sit this thing out. Be assured that everything possible is being done." But what could be and jelly-like mud formed death-traps for the countless refugees now streaming east. Perhaps the North Platte disaster had been more than anyone could take. State troops were called out, but moving two million people was not to be done in an orderly way. And still the landslip grew larger. The new cliffs gleamed in the autumn sunshine, growing higher as the land beneath them continued its inexorable descent. as a hollow roar, a shriek and a deep musical vibration like a church bell. It was simply the tortured rock of the substrata giving way. The second phase of the national disaster was beginning. was somehow to ride out the coming flood, "but like as if the land wanted to be somewhere else." Everyone in doomed Biloxi would have done well to have been somewhere Despite hopeful announcements that the wave was slowing, had virtually stopped after inundating Oklahoma City, was being swallowed up in the River afterwards recalled the hiss and scream like tearing silk as the water broke furiously on the newly exposed rock. It was the most eventual place of stability one thousand feet below the level of the new sea. Nebraska to the other. Similar hair-breadth escapes were recounted on radio and television. younger children and what provisions they could find—"Mostly a ham and about half a ton of vanilla cookies," he explained to his eventual spectacular. Her rural good-humor undamaged by an ordeal few women can ever have been called on to face, she added, "We sure wondered why flushes never came out right. Jimanettly, we'd left the king of hearts behind, in the rush!" But such lightheartedness and such happy endings were by no means typical. The world could only watch aghast as the water raced north under the shadow of the cliffs which occasionally crumbled, roaring, of eight states, and portions of twelve others, had simply vanished from the heart of the North American continent forever. It was in such a cataclysmic birth that the now-peaceful Nebraska Sea came to America. Today, nearly one hundred years after the unprecedented—and happily unrepeated—disaster, it is hard to remember the terror and despair of those weeks in October and November, 1973. It is inconceivable to think of the United States without its beautiful and economically essential curve of interior ocean. Two-thirds as long as the Mediterranean, it graduates from the warm waters of the Gulf of Mexico through the equally blue waves of the Mississippi Bight, becoming cooler and Archipelago, finally shading into the gray-green chop of the Gulf of Dakota. What would the United States have become without the 5600-mile Who can imagine what the middle west must have been like before the amelioration of climate brought about by the proximity of a warm sea? Carolina to the rich fields of New Mexico and the orchards of Montana, is directly ameliorated by the marine heart of the continent. Who today could imagine the United States without the majestic afternoon bather, thanks to the monorail connecting the highest peaks with the glistening white beaches? And though the Nebraska Sea today carries many times the tonnage of shipping in its ceaseless traffic, we have lost the old romance of river shipping. We may only guess what it was like when we look upon cars. Still, the ferry ride is certainly a welcome break after days of driving, and for those who wish a glimpse of what it must have been population decided to retain political integrity. This has resulted in the continuing anomaly of the seven "fringe States" represented scene. But this is by now no more than a petty annoyance, to raise a smile when the talk gets around to the question of State's Rights. Not even the tremendous price the country paid for its new sea—fourteen million dead, untold property destroyed—really offsets the asset we enjoy today. The heart of the continent, now open to the shipping of the world, was once dry and land-locked, cut off from the bustle of trade and the ferment of world culture. It would indeed seem odd to an American of the '50s or '60s of the last century to imagine sailors from the merchant fleets of every nation walking the streets of Denver, fresh ashore at Newport, only fifteen miles away. Or to imagine Lincoln, Fargo, Kansas City and Dallas as world ports and great manufacturing centers. Utterly beyond their ken would be Roswell, New Mexico Westport, Missouri, and the other new ports of over a million inhabitants each which have developed on the new harbors of the inland sea. Unimaginable too would have been the general growth of population in the states surrounding the new sea. As the water tables rose and manufacturing and trade moved in to take advantage of the just-created axis of world communication, a population explosion was touched off of which we are only now seeing the diminution. This new westering is to be ranked with the first surge of pioneers which created the American west. But what a difference!
