On January 14, NGS joined the Thomas Jefferson Foundation at Monticello in dedicating a survey marker that commemorates the bicentennial celebration of the Lewis and Clark expedition. The 12-inch diameter brass marker was set in the West Lawn of Monticello in October 2003.

The program included participants from the American Indian Society Color Guard, author Dayton Duncan, National Park Service Superintendent Gerard Baker, and National Park Service Director Fran Mainella. NGS director Charlie Challstrom delivered a speech dedicating the marker and presented Dan Jordan, president of the Thomas Jefferson Foundation, with a replica of the marker. David Holland, Secretary and Treasurer of the Virginia Association of Surveyors, then gave a brief background of the project and presented the original field map of the location survey to Jordan.
