The confluence area of major Montana waterways is documented here, where the Missouri River flows north past Eustis and Wheatland. The landscape is defined by the intersection of rail infrastructure and river crossings, notably the Northern Pacific Railroad Bridge and the Trident Bridge near the industrial settlement of Trident. To the south, the Gallatin River meanders toward its meeting point with the other headwaters, flanked by the communities of Logan and Carpenter.
