The 2009 ceremony at Lewis's grave was the final bicentennial event honoring the Lewis and Clark Expedition. Re-enactors from the Lewis and Clark Bicentennial participated, and official attendees included representatives from Jefferson's Monticello. Lewis and Clark descendants and family members, along with representatives of St. Louis Lodge #1, past presidents of the Lewis and Clark Trail Heritage Foundation, and the Daughters of the American Revolution, carried wreaths and led a formal procession to Lewis's grave. Samples of plants which Lewis discovered on the expedition were brought from the Trail states and laid on his grave. The U.S. Army was represented by the 101st Airborne Infantry Band and its Army chaplain. The National Park Service announced that it would rehabilitate the site.
