About this map

The small settlement of Castagne and the nearby Missouri Cutoff define the human landscape of this Carbon County region. The map reveals a sophisticated network of irrigation infrastructure essential for high-plains agriculture, including the Pleasant Valley Ditch, Underland-Ramstad Ditch, and Harney Ditch. These man-made channels divert water from natural flows like Red Lodge Cr and Willow Cr to support the surrounding ranchlands.

For genealogists and local historians, several small burial sites are documented, such as the Thiel Homestead Cem, Sunrise Cem, and the John Henry Cem. The topography is shaped by prominent rises like Jones Hill and the distinctive West Bench, with the seasonal drainage of Schroeder Gulch cutting through the southern sections. This survey documents the intersection of natural watercourses and the extensive ditch systems that have sustained this part of Montana for generations.
