On July 31, 2004, NOAA's National Geodetic Survey dedicated the geodetic commemorative marker at Omaha, Nebraska.

The large Peace Medal monument rests along the winding sidewalk between Fort Atkinson's Visitor Center and the five life-size bronze statues depicting the first meeting with the American Indians. To pay tribute to the survey monument a ceremonial plaque, furnished by the Professional Surveyors Association of Nebraska, (PSAN), was placed next to the survey cap explaining the historic significance of the Peace Medal, its latitude and longitude, and the distance from the starting point of the 'Corps of Discovery'.

To honor this bicentennial, the Professional Surveyors Association of Nebraska held a dedication on the opening day of the "Corps of Discovery II". The main speakers were John Craig, Director of the Nebraska Department of Roads, Roger Kuhn, Assistant Director of the Nebraska Game and Parks Commission and Steve Randall, National Geodetic Survey, (NGS) from Silver Spring, Maryland. Presentation of awards was handed out by Richard Hanson, President of PSAN, and the master of ceremonies was Gene Thomsen, Deputy State Surveyor. A special thanks goes out to Rex Heiden, John Slader, and Jim Swenson of the Nebraska Game and Parks Commission as well as James Richardson, NGS Advisor for their assistance in this projects success.
