The Men Who United the States: America's Explorers, Inventors, Eccentrics and Mavericks, and the Creation of One Nation, Indivisible

understand the geology of a country is to understand and then to realize all of its possibilities—its wealth, its strengths, the nature and kinds and value of its resources. Geology, after all, and without any intended pun, underlies everything. Human settlement on an unknown landscape perforce depends on a deep knowledge of what and where is potentially being settled—on whether the geology of this region suits it to farming, to mining, or to industry heavy or light; whether this range of hills is traversable, this cold prairie is cultivable, this wide river is fordable.

Eighteenth-century geology, infant science though it still may have been, offered the keys to unlock the country’s promise, bringing men out to inhabit the farther reaches of this country and create their nation. And the town of New Harmony, Indiana, was where this realization of geology’s importance was born. The town, first simply named Harmonie, was settled initially by early-nineteenth-century Germans, men and women fleeing to America much as the Pilgrim Fathers had fled two centuries before, to escape religious restrictions back home. Their piety and hard work paid off quickly, and they eventually moved on to larger quarters, selling their tiny settlement to another idealist adventurer, the campaigning Welsh socialist Robert Owen. He, flushed with the success of a millworkers’ commune that he had organized outside Edinburgh, planned to establish a utopian beachhead in America, based on socialist ideals. He renamed the former German village New Harmony; and once he had settled during the winter of 1825, he invited like-minded idealists to join him. Such was the educational reputation of Owen’s earlier Scottish experiment that New Harmony became an immediate magnet for intellectuals, philosophers, teachers—and, in particular, scientists. Geologists, most notably, pitched in with a special enthusiasm, such that at the peak of New Harmony’s fortunes, no fewer than seven geologists of considerable later distinction could be counted among the inhabitants. This tiny town bri...

New Harmony can fairly be regarded more specifically as the birthplace of American geology—not least because Robert Owen’s closest colleague and ideological soul mate, an equally eccentric visionary who came to join him on the banks of the Wabash River, is generally acknowledged today to be American geology’s founding father.

He first decided to devote much of his remaining life to promoting educational reforms among America’s working classes. He vowed, as Robert Owen had already vowed, unbeknownst to Maclure, that the farmer, the miller, and the forge master would each have the same access to society’s potential as he and his wealthy peers had already been granted. It might take him years, but he would at least now begin to make plans. At thirty-six, he believed himself young enough and fit enough to take on such a challenge. He had already achieved great eminence among the East Coast thoughtful: he was a leading light in the fiercely intellectual American Philosophical Society, founded by Benjamin Franklin, and would later go on to help found and run the American Academy of Natural Sciences, the oldest such institution in the country today. He believed deeply in the unifying powers of democratized science.

He first toyed with the science during a brief stay in Europe, delving into the small mysteries of its nomenclature at the very time when the numerous schisms that plagued the calling were at their most dramatic. Perhaps no science has ever been caught up in such turmoil. On the one hand, geologists were busily unleashing themselves from centuries of dogmatic interference from the church. The less pious of their number were no longer content to believe unquestioningly in such literal Bible-based teachings as the creation of the earth on a precise October date in 4004 BC, for instance.

is surely a universal truth that men and women who choose voluntarily to pack up everything, acquire a wagon, set off down a rutted track into the sunset, and then endure weeks and months of privation, misery, and real danger in order to create new homes for themselves countless miles elsewhere must have a powerful reason for doing so. Modern America’s very existence is based on the awe-inspiring reality that thousands upon thousands made this very choice. And at first blush it appears they had just as many thousands of reasons for setting forth toward the sunset.

Nearly all were going off to the West because they imagined a better and more congenial life there. Perhaps some were afflicted by a goading restlessness, but only a few went out on a whim. Some were drawn by reasons religious, others were compelled by a need to escape—to get away from political persecution, from the hand of the law, the clutch of a pestilence,* the misery of a failed romance, or the stench of an unsavory past. A number in America’s Eastern and Southern states found the whole business of segregation and slavery unpalatable, and imagined that out west they might encounter a more tolerant and liberal atmosphere.

But for most, the West was simply the Promised Land. “Eastward I go only by force,” said Thoreau, “but westward I go free.” And the pioneers who were bold enough to head in that direction did so, generally speaking, imbued with a spirit of ambition and adventure and an unyieldingly optimistic sense of enterprise. And yet—what was it, more specifically than all of their stated reasons, that truly provided the lure? What intelligence was it that had produced the necessary temptation—the impetus, the final trigger, that decided a hitherto settled Easterner to obtain a wagon, to pack up all his belongings, to say farewell to scores, and then to head off for thousands of miles into the Western unknown? The answer almost alway...

Continentalism—the notion that had been so eloquently advocated by John Quincy Adams in his 1811 letter home—was then swiftly realized. America’s Manifest Destiny became a sure reality; the Pacific coast became America’s sole remaining frontier; and in time, and for a while, the Pacific Ocean became an essentially American ocean.

The countryside over which these armies of migrants crossed is some of the most desolate and beautiful in all creation. But even in their crossing it, the travelers did not really come to know it. To almost all of them, the American West was a vastness that had to be crossed, not considered. The plains, passes, and peaks were all to be endured, not analyzed. The destinations were what counted most.

These were men who were dispatched across the country by their superiors based at the West Point Military Academy on the west bank of the Hudson—which then was not a school for teaching warfare, tactics, and leadership, but rather the country’s foremost engineering college.
