📍 A group of DGR surveyors traveled to Mount Rushmore for the NSPS - The National Society of Professional Surveyors America 250th Celebration on Oct. 19. Surveyors from across the country gathered for the event, which included a special medallion dedication recognizing America’s 250th anniversary.

Adding to the celebration, SD Governor Larry Rhoden proclaimed the day as National Surveyor Day in the state.

❗️Fun fact: Three of the four presidents depicted on Mount Rushmore, Washington, Jefferson, and Lincoln, worked as land surveyors before taking office. A pretty fitting place for a national gathering of surveyors! dgr.com
