Ripples from La Prairie Voyageur Canoes: Chapter Ten: The Long Portage Ends, (1846

The last years settled over French Prairie like a long, mild evening.

François Rivet, well past ninety, lived on the claim south of the St. Paul Mission in the company of memory and the quieter labors of age. The great movements of his life were finished. There were no more brigades to join, no more rivers to fight upstream, no more winters in the mountains with powder running low. The work that remained was the work of any old farmer: watching the weather, advising the younger men, sitting in the sun when the weather was kind, and enduring the damp cold when it was not.

Antoine and Joseph kept their own households nearby. The three claims formed a small family cluster of fields, cabins, and shared labor. Grandchildren appeared and grew. The old man who had once danced on his hands for the Mandan was now the white-haired elder who held infants at the baptismal font and stood as witness when the next generation married. The mission registers continued to carry his name in the steady handwriting of the priests.

Around him the Oregon Country completed its transformation. The Provisional Government gave way to territorial status after the Treaty of 1846 settled the boundary with Britain at the 49th parallel. American settlers poured in by the thousands. The French-Canadian families who had pioneered the prairie adjusted as best they could—learning the new land laws, taking out citizenship when it became necessary to secure their claims, watching the language of the valley shift year by year toward English. Rivet himself was naturalized as a citizen of the United States on 9 September 1852. The date is almost painfully late; he had less than three weeks to live. It was a final, practical act to protect the land for those who would come after him.

Therese remained at his side. The Salish woman who had shared thirty years of lodges, trail camps, and company posts now shared the slower seasons of the Willamette. Their long country marriage, formalized at last in 1839, had outlasted empires and the fur trade itself. Friends and neighbors still spoke of them as a single household: Old Rivet and his wife.

In late September 1852 the end came. On the 27th (some records say the 25th), François Rivet died at his house on the claim. He was ninety-eight years old by the baptismal record of Saint-Sulpice, or ninety-three by some of the contemporary notices that undercounted his age. The precise number mattered less than the span. He had been born in the last years of New France, had paddled the Missouri before Lewis and Clark, had wintered beside Fort Mandan, had survived the Bitterroot massacre, had interpreted for the great Snake Country brigades, and had lived to see the Oregon Country become American territory. No other man associated with the Corps of Discovery is known to have remained in the West and died there at such an age.

Therese followed him within three weeks. On or about 13 October 1852 she too was gone. The couple who had begun their life together in a Salish lodge in the mountains were buried in the Old Saint Paul Mission Cemetery, in the sandy soil of the prairie they had chosen for their last home.

The sons carried the name forward. Antoine remained on the land, raised a large family, and left descendants who stayed in the valley. Joseph died around the same period as his parents. The blood of Maurice Rivet of La Rochelle, of the voyageurs of L’Assomption, of Therese Tête Platte of the Salish, and of the long, hard schools of the Missouri and the Columbia continued in the mixed-blood families of French Prairie and beyond.

François Rivet’s life had been a single long portage—across languages, empires, rivers, and the turning of an age. He began it as a child of the Saint Lawrence parish and ended it as one of the oldest settlers of the Willamette. In between he had belonged to the river, the mountains, the freeman’s camp, the company post, and finally the quiet claim on the prairie. He left no written memoir. The record of his days is scattered across notarial contracts, expedition journals, company lists, mission registers, and the memories of those who knew him as Old Rivet.

Yet the shape of the life is clear. He adapted without losing himself. He formed a family across cultures and kept faith with it. He worked until work was no longer possible, and then he rested. When the final portage came, he had already carried his pack farther than almost any man of his generation.

The rivers he traveled still run. The prairie where he died is still farmland and memory. And somewhere in the living descendants of Antoine Rivet and the wider kinship of French Prairie, a trace of that stubborn, durable voyageur blood continues—quiet evidence that François Rivet of Saint-Sulpice once passed this way, and stayed.
