In the 1860's, land speculators in Minnesota and the Dakota Territory expected that a great city would rise where the railroad crossed the Red River of the North. In 1872, after the Northern Pacific Railroad laid its first tracks across the river, it brought settlers, capital, and access to Eastern markets and gave birth to the twin cities of Moorhead and Fargo. Historian Carroll Engelhardt's Gateway to the Northern Plains chronicles the story of Fargo and Moorhead's birth and growth.
