There are rivers that divide a landscape. And there are rivers that divide the imagination. In Texas, the Pecos managed to do both. For generations, the words West of the Pecos meant something. They meant you were leaving one world and entering another. A harder world. A drier world. A place where towns were separated by miles and miles of country that seemed determined to remind human beings that they were not necessarily in charge. Today, we can drive across that country in an air-conditioned automobile. We carry water in plastic bottles. We have GPS. Gas stations. Cell phones. And even then, there are stretches of West Texas where you can look out the window and think: Who in the world decided to live here? Now imagine making that decision in 1881. This is the Hidden History of Texas. And today we're headed west. To Pecos. Before there was a town called Pecos, there was the river. The Pecos begins in the mountains of northern New Mexico and runs south and southeast across an increasingly dry landscape before eventually joining the Rio Grande. The Spanish knew portions of it as the Río Puerco—the dirty river. And depending upon where you encountered it, the Pecos could be a source of life, an obstacle, a landmark, or a warning. For Indigenous peoples, the river and the country surrounding it had been part of a much larger landscape of travel, hunting, trade, and settlement long before Europeans arrived. And that is worth remembering because we have a tendency to tell the history of West Texas as though the country sat empty until ranchers, soldiers, and railroad men arrived. It didn't. People had been crossing and using this landscape for thousands of years. But the environment determined the rules. Water determined where you could travel. Water determined where animals could survive. Water determined where people could stay. And if you didn't understand the country, the country could kill you. By the middle of the nineteenth century, Americans were beginning to move through the region in greater numbers. Soldiers. Surveyors. Freighters. Cattlemen. Travelers heading farther west. The Pecos became one of those psychological markers on the map. Cross the river and you were entering country that seemed even more remote. This was the world in which military posts such as Fort Stockton and Fort Davis became so important. They protected roads. They guarded travelers. They supported military campaigns. And slowly they helped open West Texas to increased settlement. But opening a country and actually convincing people to live there are two very different things. The first Anglo settlements along the Texas portion of the Pecos were sparse. And there was a very good reason. Living there was hard. Not Hollywood hard. Not gunfight-at-high-noon hard. Everyday hard. Finding dependable water. Building shelter. Keeping livestock alive. Surviving summer heat. Surviving winter cold. Getting supplies. Dealing with isolation. Repairing something when the nearest replacement might be days away. Having a child when there wasn't a doctor down the street. Getting sick when there wasn't a hospital. Losing livestock and knowing that your livelihood had just disappeared with them. That kind of hard. The sort of toughness that rarely makes it into Western movies. Then, in 1881, everything changed. The railroad arrived. The Texas and Pacific Railway was pushing westward across Texas toward El Paso. And when those rails reached the Pecos River country, they did something railroads did all across the American West. They created a reason for a town to exist. Pecos began as a cattle camp east of the river, but the developing community shifted westward as the railroad established its depot. For a while it was Pecos Station. Then Pecos City. Eventually simply Pecos. But the railroad was more than transportation. It changed distance. Before the railroad, getting cattle, supplies, equipment, mail, or people across West Texas required time—and a considerable amount of luck. The railroad connected Pecos to markets hundreds of miles away. Suddenly cattle raised in West Texas could reach distant buyers. Supplies could arrive regularly. People could come. Businesses could survive. A settlement became a town. And by the middle of the 1880s, Pecos had about 150 residents. That doesn't sound like much today. But put 150 people in that country in 1885 and you've got yourself a community. And those people needed water. Not simply drinking water. If Pecos was going to become more than a railroad stop and cattle-shipping point, somebody had to figure out how to make the desert produce something. So they turned again to the river. Irrigation wasn't new to the Southwest. Indigenous peoples had understood irrigation agriculture centuries before Europeans arrived. Spanish and Mexican communities used irrigation systems throughout the region. But late nineteenth-century developers began trying to transform irrigation into something larger. An economic engine. Canals were constructed. Land was promoted. Settlers were encouraged to believe that with enough water, West Texas could bloom. And sometimes it did. Nearby communities produced grapes. Peaches. Pears. Melons. And Pecos itself eventually became famous for cantaloupes. Imagine arriving from somewhere green, looking across that dry West Texas country and hearing someone say: We're going to grow melons here. You might have questioned their judgment. But they did it. Water made the difference. Which meant controlling water became increasingly important. And that story—who gets the water, how much they get, and what happens upstream—is one that would follow the Pecos River well into the twentieth century. But cattle remained king. And cattle brought cowboys. Which brings us to one of Pecos's favorite stories. The world's first rodeo. According to Pecos tradition, on July 4, 1883, cowboys from several ranches gathered to settle an argument. Who was the best roper? Who was the best rider? There was only one reasonable way to find out. Get everybody together and make them prove it. The contest held at Pecos became one of the earliest documented rodeos in American history and apparently the first known rodeo to award prizes. And Pecos has proudly advertised itself as the home of the world's first rodeo ever since. Now... You know me. Whenever somebody says something was unquestionably the first anything in history, I start checking. And Pecos has competition. Deer Trail, Colorado, records a bronco-busting contest in 1869. Buffalo Bill Cody staged an exhibition of cowboy skills at North Platte, Nebraska, in 1882. Prescott, Arizona, held an organized rodeo in 1888 and became one of the earliest to charge admission. So was Pecos really the first rodeo? That depends partly on what you mean by rodeo. And that is usually how these historical arguments work. But Pecos's 1883 contest absolutely belongs among the earliest events in the development of what became modern rodeo. And perhaps the argument over who was first is less interesting than what the contest tells us. Cowboys were turning the skills of everyday ranch work into competition. Roping. Riding. Handling livestock. These weren't originally sports. They were jobs. Hard jobs. And somewhere along the way, somebody said: I can do that better than you. And rodeo was born. That may be the most Texas origin story imaginable. But there is another Pecos story that deserves mentioning. Because the railroad didn't merely reach Pecos. Railroads had to conquer the Pecos River itself. Farther downstream, railroad engineers encountered the enormous canyons near the river's junction with the Rio Grande. The first rail crossing required steep grades, tunnels, trestles, and tracks blasted along canyon walls. It was expensive. Dangerous. And inefficient. So engineers eventually decided to do something audacious. Instead of taking the railroad down into the canyon, they would carry it across the top. The Pecos Viaduct was completed in 1892. More than 320 feet high, it was then the highest railroad bridge in the United States and one of the highest bridges in the world. Think about that. In a region where earlier travelers worried about finding enough water to survive, engineers were now building a steel railroad bridge more than three hundred feet above the river. In barely a generation, the relationship between people and the Pecos had changed dramatically. The river was still an obstacle. But increasingly, people believed obstacles could be engineered away. And maybe that's what makes Pecos such a good place to stop after our last visit to La Junta. At La Junta, generations of Indigenous communities had learned how to live within the limits of the desert. They understood where water was. They farmed the floodplain. They hunted. They traded. They adapted themselves to the country. By the late nineteenth century, newcomers increasingly approached West Texas with a different idea. Instead of adapting themselves to the landscape, they would try to adapt the landscape to them. Build a railroad. Dig a canal. Dam the water. Drill a well. Build a bridge. Plant crops in the desert. Bring cattle by the thousands. Build a town. Sometimes it worked. Sometimes it didn't. And sometimes the consequences didn't become apparent until much later. But you have to admire the audacity. I've been to Pecos. ...
