The Cairn is located directly on the United States and Canadian Border, flanked by each country’s flagpole on the designated side. The Cairn is built of aboriginal hammerheads collected by children in the surrounding areas. In July 17, 1960, the globe of red granite with etched meridian lines, a gift from Great Northern Railway company of St. Paul, Minnesota, as a memorial to its founder, Canadian born James J. Hill, was added to the top of the Cairn. On the face of the Cairn it states: “To God in His Glory… We two nations dedicate this garden and pledge ourselves that as long as men shall live we will not take up arms against one another.”
