Arriving the following year, the couple quickly rose to both wealth and local prominence, with Charles Dye prospering as a lawyer and real estate investor.

"[3] "At the turn of the [20th] century Eva Emery Dye replaced [Frances Fuller] Victor as Oregon's best-known historical researcher," wrote Richard Etulain in 2001.

Reliable historical information about Sacagawea is extremely limited; even the correct spelling of her name (Lewis and Clark rendered it eight different ways) and the date of her death are under dispute.

As the Oregon History Project observes: The Expedition journals make note of her service as an interpreter and mention that she pointed out familiar landmarks when they entered Shoshone territory.

[6] While her previous book included fictional stylistic elements but conformed on a narrative level to known facts, The Conquest was notably unfettered by adherence to the historical record.

Dye's portrayal of Sacagawea ascribed to her imagined features (no portrait or description survives), and postulated that her role was integral to the expedition's success, to the extent that she should be commemorated equally with Lewis and Clark: Sacajawea's hair was neatly braided, her nose was fine and straight, and her skin pure copper like a statue in some Florentine gallery.

In 1905 The National American Woman's Suffrage Association, convening in Portland, unveiled a statue, Sacajawea and Jean-Baptiste, by sculptor Alice Cooper of Denver.

This recognition of the assistance rendered by a woman in the discovery of this great section of the country is but the beginning of what is due...[9]Following the ceremony, Dye formally presented the statue to the soon-to-open Lewis and Clark Centennial Exposition, where it was seen by an estimated three million visitors.
