1983 Map of Nelson Island

About this map

Missouri River currents dominate this 1983 survey of Cascade County, where the waterway creates a significant physical boundary near Nelson Island. The landscape is defined by the convergence of numerous named drainages, including Muddy Creek, Little Muddy Creek, and Chestnut Valley Creek, illustrating the complex hydrology of the Montana plains. The Burlington Northern railroad follows the river's path, tracing the vital transportation corridor that linked these rural ranching and farming lands to broader markets.
