Cascades of the Columbia, Oregon   November 4, 1805

Sagittaria latifolia is not a plant that was collected during the expedition but it was an important and desirable source of food for the natives in a 70 mile stretch of the Columbia River (from Clark County, Washington to Multnomah County, Oregon) and became familiar food to the Corps.  Both Lewis and Clark wrote about its trading value to the local tribes and about how the women gathered the bulbs from the roots in the shallow banks of the rivers.
