Following in the Footsteps of Lewis & Clark
Corps of Discovery II Markers
This brass Corps of Discovery II marker commemorates the symbolic start of the Lewis and Clark expedition. Initiated by Thomas Jefferson, the expedition began to explore and map America in 1803.To honor Lewis and Clark's contributions to mapping, NOAA’s National Geodetic Survey (NGS) is installing a series of commemorative markers along the route that Lewis and Clark traveled, beginning in Monticello in Virginia and ending at Fort Clatsop in Oregon. NGS is positioning these markers using modern techniques, including the satellite-based Global Positioning System. The markers will become part of the National Spatial Reference System (NSRS), the federal standard and foundation for all positioning and navigation activities in the United States.
