The site commemorates the role the Whitmans played in establishing the Oregon Trail. Marcus and Narcissa Whitman were Christian missionaries who came over in covered wagons in 1836.
They built their mission on this site among the Cayuse Indians. Narcissa Whitman and Eliza Spalding were the first white women to cross the continent overland.
After ten years of working with the Indians, the mission ended when the Cayuse attacked and killed the Whitmans and 11 others and took more than 60 hostages
. A hilltop monument has been erected at the site. There is a picnic area but camping and fires are not permitted.
