About three miles east of Louisville was the Vermillion Crossing of the Oregon Trail operated by Louis Vieux.  Vieux is buried in the Vieux Family Cemetery on top of a hill.  Nearby, on the banks of the river, is a [[cholera]] cemetery from 1849, which is estimated to contain at least fifty graves, although only two stones—both native sandstones—remain.  The Louis Vieux Elm Tree is across the river and is estimated to be over 300 years old.  The tree had been afflicted with [[Dutch elm disease]], a lightning strike and vandalism and efforts were taken to protect and shelter the tree's stump.  In August 2011, the stump was destroyed by fire.<ref>{{Cite web | url=http://cjonline.com/news/2011-08-24/arson-claims-historic-elms-stump | title=Arson claims historic elm's stump }}</ref> Near the tree are the graves of seven unknown soldiers.
