Marie Aioe Dorion died in September 1850.

She was about 64 years old.

She had been born into the Ioway nation in a period when the Ohio Valley was still the American frontier and the Pacific Northwest was terra incognita to the United States government.

She had lived through the second transcontinental crossing, through the establishment and surrender of Fort Astoria, through her husband’s death and her own winter survival, through the transformation of the Pacific Northwest from a fur-trade world to an American territory.

She had outlasted the political entity that sent the Hunt expedition: the Pacific Fur Company effectively ended in 1813 when Fort Astoria was sold to the North West Company.
