Narcissa Whitman — 1836, the First Crossing

In 1836, a decade before the great family migrations, Narcissa Whitman and Eliza Hart Spalding rode west with their missionary husbands and became, by the long-standing account, the first Euro-American women to cross the Continental Divide overland. They did it not on a wagon highway but on a thin, half-mapped fur-trade route, attached to the American Fur Company’s annual supply caravan, through country no white woman had ever traveled. Their arrival upended an assumption that had quietly governed the whole question of westward settlement: that the journey was simply too hard for women to make. If two women could reach the Oregon Country, families could follow — and within a few years, they did.

Narcissa Prentiss was a bright, devout young woman from western New York, swept up in the religious fervor of the 1830s and burning to serve as a missionary. The American Board of Commissioners for Foreign Missions, however, would not send a single woman to the frontier — so when it accepted the physician Marcus Whitman, marriage became Narcissa’s passage. She and Marcus wed in February 1836 and left almost at once. Joining them were Henry Spalding, a former suitor of Narcissa’s, his wife Eliza, and the young mechanic William H. Gray. It was, by any honest reckoning, an awkward and strained little company, bound together by faith and by the sheer audacity of what they meant to do.

The party traveled up the Platte, attended the riotous 1836 fur-trade rendezvous on the Green River — where trappers and the Native nations who gathered there crowded around to see the two women — and crossed South Pass on the Fourth of July. They reached the Hudson’s Bay Company post at Fort Vancouver, and then the Whitmans established their mission at Waiilatpu, on Cayuse land near present-day Walla Walla, Washington, while the Spaldings settled among the Nez Perce at Lapwai. Narcissa’s letters and journal, written home to family she would never see again, are among the foundational documents of the overland trail — vivid, ardent, and at times painfully revealing.

Her story did not end in triumph. The mission among the Cayuse grew strained as the trickle of American emigrants she had helped make possible became a flood passing through Cayuse country, carrying disease ahead of it. In 1847 a measles epidemic killed many of the Cayuse — a people with no immunity to it — even as white children in the mission’s care recovered. On November 29, 1847, in the violence that followed, Narcissa and Marcus Whitman and others were killed. The woman whose crossing had helped open the trail was among the first Americans to die for what that opening set in motion.
