Lewis described bear grass on June 15, 1806, on the Lolo Trail in the Bitterroot Mountains, noting “There is a great abundance of a species of bear-grass which grows on every part of these mountains.” The plant was first called “beargrass” by members of the expedition. Its leaves were extensively used by Northwest Native peoples for weaving intricate waterproof baskets and hats.
