Latitude, Longitude: 46.060397, -118.906703

Madame Dorion Memorial Park is located at the junction of Washington State Highway 12 and Highway 730, at Columbia River Mile (RM) 315 (Lake Wallula), where the Walla Walla River meets the Columbia. During winter of 1811-1812, an advance party of the first fur traders reached the Columbia River from Montreal, Canada. With them was Marie Dorion, an Iowa Indian, who was the second women to come west overland -- the first being Sacajawea, with Lewis and Clark. Marie was the wife of Pierre Dorion, the interpreter for the expedition. She came west with her two children and she inspired her companions by the manner in which she bore the hardships and discomforts of the journey with fortitude. In 1931 the Madame Dorion bridge was built across the Walla Walla River, the remains of which can still be seen at the mouth of the Walla Walla. The nearby 46-acre day-use and camping park is also named in her memory.
