Washington Park, in Portland, features a very famous statue of Sacajawea. It is a 34-foot bronze effigy of Sacajawea. It was first unveiled in 1905 at the Lewis and Clark Centennial in Portland. It was the first statue of a woman unveiled in America. Among those present at the unveiling were Susan B. Anthony (civil rights advocate and suffragette), Anna Howard Shaw (civil rights leader and suffragette), Abigail Scott Duniway (human right advocate and suffragette), and Eva Emery Dye (author of the book The Conquest which highlighted the legacy of Sacajawea and helped propel Sacajawea to her legendary status).

The project was promoted and paid for by subscriptions solicited nationwide by a group of Portland women headed by Mrs. Sarah Evans. The sculpture was done by a woman, Alice Cooper, and required more than 20 tons of Oregon copper. In April 1906 the statue was placed in its current location in Washington Park.
