About this map

The confluence of the Yellowstone River and the Clarks Fork forms the geographic heart of this mid-century survey, which documents a landscape defined by industrial irrigation and rail logistics. The settlement of Edgar serves as a local hub, anchored by its Grain Elevators and a strategic junction of the Chicago Burlington and Quincy and Northern Pacific railroads.

An intricate network of water management features, including the Edgar Canal, Bartlett Canal, and Orchard Canal, illustrates the scale of the Missouri River Basin development project during this era. To the east, the terrain rises sharply toward Two Bear Ridge, while local history is marked by features like the Rockvale Cemetery and the industrial activity of a Gravel Pit. The map captures a moment when surface irrigation was essential to the valley's agricultural economy.
