Everyone—all the geologists, at any rate—had known about the Kiowa Fault for years. That was before there was anything very interesting to know about it. The first survey of Colorado traced its course north and south in the narrow valley of Kiowa Creek about twenty miles east of Denver almost from the Canadian border well south of the New Mexico-Texas line. It is not really surprising that it took so long to figure out the connection. The population of the states affected was in places as 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 everywhere east of the Fault, to almost twenty miles away, the now-familiar lurch and steady fall had already sent several thousand Coloradans scurrying for safety. and rapidly approaching the border of New Mexico to the south. Trinchera and Branson were totally evacuated, but even so the over-all Away to the east the situation was quiet but even more ominous. Tremendous fissures opened up perpendicular to the Fault, and a general subsidence of the land was noticeable well into Kansas and Nebraska. The western borders of these states, and soon of the Dakotas and Oklahoma as well, were slowly sinking. the land shuddered downward in gasps and leaps. Springs burst to the surface in hot geysers and explosions of steam. The downtown section of North Platte, Nebraska, dropped eight feet, 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 way north along the Little Missouri. South, it ripped past Roswell, New Mexico, and tore down the Pecos toward Texas. All the upper reaches of the Missouri were standing puddles by now, and the Red River west of Paris, Texas, had begun to run backward. Soon the Missouri began slowly slipping away westward over the slowly churning land. Abandoning its bed, the river spread uncertainly across with a gigantic wave of refugees. Rails, roads and air-lanes were jammed with terrified hordes who had left everything behind to crowd eastward. All through October hollow-eyed motorists flocked into Tulsa, Topeka, Omaha, Sioux Falls and Fargo. St. Louis was made distributing center for emergency squads which flew everywhere with milk for babies and by a mob of would-be passengers in Bismarck, North Dakota. Federal and State troops were called out, but moving two million people was not to be done in an orderly way. second phase of the national disaster was beginning. The noise traveled due east at better than 85 miles per hour. In its was a sigh and a great cloud of dust, and Oklahoma subsided at the astounding rate of about six feet per hour. At Biloxi, on the Gulf, there had been uneasy shufflings under foot all about the same moment. The tidal wave which was to gouge the center from the U. S. marched on the land. From the north shore of Lake Ponchartrain to the Appalachicola River in Florida, the Gulf coast simply disappeared. Gulfport, Biloxi, had swept over every town from Dothan, Alabama, to Bogalusa on the Louisiana-Mississippi border. north. Chicot, Jennie, Lake Village, Arkansas City, Snow Lake, Elaine, Helena and Memphis felt the tremors. The tormented city shuddered through the night. The earth continued its descent, eventually tipping forming, overtopping the wave's leading edge as towns, hills and the thirst of the soil temporarily broke the furious charge. Washington announced the official hope that the Ozarks would stop the wild gallop of the unleashed Gulf, for in northwest Arkansas the land rose to over 2,000 feet. But nothing could save Oklahoma. By noon the water reached clutching fingers around Mt. Scott and Elk Mountain, Despite hopeful announcements that the wave was slowing, had virtually stopped after inundating Oklahoma City, was being swallowed up in the desert near Amarillo, the wall of water continued its advance. For the the Gulf. Schwartzberg and his geologists advised the utmost haste in evacuating the entire area between Colorado and Missouri, from Texas to North Dakota. Sterling, Colorado, on Sidney, Nebraska, on Hot Springs, South Dakota. precarious havens for half-drowned humanity. Waves bit off a corner of Missouri, flung themselves on Wichita. Topeka, Lawrence and Belleville were the last Kansas towns to disappear. The Governor of Kansas went down with his State. Daniel Bernd of Lincoln, Nebraska, was washed up half-drowned in a cove Nebraska to the other. Similar hair-breadth escapes were recounted on radio and television. western Nebraska and the Dakotas. But when the waters came to rest along what is roughly the present shoreline of our inland sea, it was almost the entirety 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 it graduates from the warm waters of the Gulf of Mexico through the equally blue waves of the Mississippi Bight, becoming cooler and greener north and west of the pleasant fishing isles of the Ozark Archipelago, finally shading into the gray-green chop of the Gulf of Dakota. What would the United States have become without the 5600-mile coastline of our inland sea? It is only within the last twenty years lifetimes. Even so, the commercial fisheries of Missouri and Wyoming contribute no small part to the nation's economy. Who can imagine what the middle west must have been like before the Now, ending as it does at Memphis and drawing its water chiefly from the Appalachian Mountains, it is only a slight remnant of what it was. 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 And transcontinental shipping is somewhat more difficult, with trucks Nebraska Sea. We shall never know what the United States was like with its numerous coast-to-coast highways busy with trucks and private 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 like, there is always the Cross-Canada Throughway and the magnificent U. S. Highway 73 looping north through Minnesota and passing through the giant port of Alexis, North Dakota, shipping center for the wheat of Manitoba and crossroad of a nation. The political situation has long been a thorny problem. Only tattered Kansas seemed, for a time, ready to merge with contiguous Missouri, but following the lead of the Arkansas Forever faction, the remaining population decided to retain political integrity. This has resulted in the continuing anomaly of the seven "fringe States" represented in Congress by the usual two Senators each, though the largest of them is barely the size of Connecticut and all are economically are still families who proudly call themselves Oklahomans, and the Oklahoma Oil Company continues to pump oil from its submerged real estate, the state has in fact disappeared from the American political 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. 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 west. But what a difference! Vacation paradises bloom, a new fishing industry thrives her water road is America's main artery of trade, and
