“ With the completion of the Southern Pacific Railroad to Yuma in 1877, river trade abruptly ceased. Today the crumbling ruins of ghost towns and mining camps along the river, like the once prosperous "Arizona Fleet," are but recollections of an age gone by. Its significance, however, cannot be overestimated; indeed, the history of Arizona and the development of the Southwest, in many respects, can be told in terms of the development of steam navigation on the Colorado River. ”
