On Sunday, November 4, while the expedition team was building its heart-shaped stockade (a fort “so strong to be almost cannonball proof,” it was noted), the French Canadian trader named Toussaint Charbonneau arrived from his home in a nearby Hidatsa village, asked for work as an interpreter, and was hired more or less on the spot.
Charbonneau had worked for the North West Company for some years and had lived with the Hidatsa most of that time. We know from the expedition diaries just a little of his appearance—that he was small and dark—and a little more of his character; he was said to have been cowardly and aggressive by turn, valued initially only as a translator, though later found to be indispensable for expedition morale as a talented maître de cuisine. But though his early worth may have been trifling, that of the younger of his two wives, Sacagawea, has since become inestimable—even if her value may have been magnified and driven by the popular demand for compelling narrative, and maybe also by a need to introduce a decisively female personality into the largely male-dominated world of the Western story.
No one has the slightest idea of what Sacagawea looked like, though there has been much speculation and invention. Fanciful images of her—in oils, watercolors, mosaics, pastels, cartoons—are plentiful. The Iowa-born white all-American beauty Donna Reed played her in one older movie (with Charlton Heston playing Clark and Fred MacMurray as Lewis), and more recently a Japanese Cherokee actress named Mizuo Peck did so in two others. Sacagawea stamps, mountain peaks, and rivers abound. The eighteen best-known American statues8 of Sacagawea usually display a tall, robed woman of classically noble bearing, invariably carrying, papoose-style, the boy child she bore in camp in February 1805. His name was Jean-Baptiste, but the expedition members more familiarly called him Pomp. (Clark could never get his tongue around Sacagawea’s proper name and called her Janey instead.)
But while the artistic world might allow some license, the United States Mint is more severe in its demands. To present as accurately imagined a profile as possible for the gold-tinted Sacagawea dollar coin required some rather more intelligent speculation. The coin artist chosen by the Treasury eventually chose as her model a twenty-two-year-old college student named Randy’L He-dow Teton, a Shoshone from Idaho who won some lasting fame as the girl on the coin and has since become a motivational speaker for the American Indian cause.
By general consensus Sacagawea is thought to have been a Shoshone from the mountains of Montana or Idaho captured by a Hidatsa raiding party. Many others claim evidence that suggests quite the opposite: that she was a Plains Indian, a member of the Hidatsa tribe all along, who had actually been captured by Shoshone raiders and spirited back to their lair in the Rockies, from which she escaped and managed to get all the way back to the Plains with the help of (the story at this point somewhat straining belief) a party of sympathetic wolves.
To judge from the expedition diaries, in which Sacagawea is seldom named as anything but “the Squaw,” there is little evidence she did a vast amount for the explorers. There is no suggestion, in particular, that she enjoyed an affair with Clark, as Donna Reed so luridly did with Charlton Heston, though the fact she gave him two dozen white weasel tails as a Christmas present was apparently enough to set Hollywood’s imagination going. Her quick thinking may once have saved some of the expedition papers from getting waterlogged when one of the pirogues tipped over. She was helpful in recognizing parts of the Western landscape from her childhood memories, and she was able to nudge the scouts to cross a particular mountain pass she knew. She was helpful as a translator and interpreter of the Shoshone language and of those other tongues that were its linguistic kin, and she knew a little French, as did Captain Lewis.
Probably her most valuable contribution was her simple presence. She was a Native American, a woman, and a mother. She traveled with her child. Any expedition that included so innocent a member could not—at least to the many Native Americans who might be encountered—pose a threat of any kind. Sacagawea thus became, unwittingly if not unwillingly, the key that opened the gates of the West and allowed the white men through.
When the winter broke and the prairie ice had begun to melt, the party set off again. They sent their big iron boat back downriver, laden with reports, specimens,9 and booty for the White House. But in their two original pirogues, together with half a dozen newly made cottonwood canoes, Lewis and Clark, along with most of their soldiery, their new interpreters, and Sacagawea and Pomp, set off upstream. It was April 7, 1805.
There was a general mood of excitement and no little regret at leaving, even among the men. During the previous six months, there had been plenty of sexual activity—the Mandan Indians were generous in offering their wives’ favors to the visitors, and the irritations of syphilis (with which many of the locals had been infected, reputedly by the French trappers) and the frequent need for mercury-ointment treatments were getting frankly tiresome. “We were now about to penetrate a country at least two thousand miles in width,” Meriwether Lewis wrote later, apparently without any intended punning, “on which the foot of civilized man had never trodden.”
At first there were many miles of loneliness and heartache—the plains desolate, the rivers shallow and fast with snowmelt, the winds “violent” and incessant, and the breath of Canada—for the territory they explored was just a few miles south of the present boundaries of Manitoba and Saskatchewan—intense and unpleasantly chill. Initially they did not encounter any Indians, other than a dead man they found on a specially built coffin-platform, offerings to the gods scattered beside him. But they did see a good deal of new wildlife: the terrifically dangerous and nearly unkillable grizzly bears most notably, as well as gophers, bald eagles, mule deer, bighorn sheep, prairie rattlesnakes, a kind of avocet, and a snipelike bird now called a willet.
There were new plants, too—such as the just-about-edible white-apple-like prairie turnip (which Sacagawea munched and seemed to enjoy) and in the drier plains the prickly pear, which painfully abraded the soldiers’ feet during the ever-more-necessary portages. And there were minerals, most especially long outcrops of the coal that is so important a part of the economy of the western plains today. The immense Union Pacific and BNSF coal trains that rumble along the horizons on their way out of the region today provide a visually appropriate kind of mobile legacy, a memorial to the expedition that first noted the wealth underground.
A month later the men, still on the ever-narrowing Missouri, were past the confluence with the Yellowstone River and two weeks later still were gliding through a peculiarly harsh landscape that is nowadays known as the Missouri Breaks, lying within the boundaries of the giant state of Montana. Lewis loved the place. His writings here were more cheerful and lyrical than at almost any other place in the odyssey. He even sees a peculiar beauty in the strange bleakness of the landscape, where the river twisted through the loneliness, with its white canyon cliffs speared through with dark patches of volcanic rocks that hint at the mountains that we now know are ahead. That the Breaks, a region so far away from the main western trails, a territory that is sparsely settled and has been largely unpopulated and unfarmed for most of its history, would later become infamous as a hiding place for outlaws and brigands only adds to an allure that Lewis can never have imagined.
Both Lewis and Clark believed that an immense range of mountains lay some way before them, and Clark first spied them from the Missouri Breaks. The distance had unrolled furiously in the weeks before: they had now done 2,387 miles since leaving Saint Louis. It was Sunday, May 26:
