About this map

Sonnette serves as the focal point for this 1960s survey of the Powder River country, where ranching and early mineral exploration shaped the high plains. The landscape is defined by the winding course of Pumpkin Creek and its many tributaries, including Sugar Run and Dry Creek. The map documents the scattered rural infrastructure of the era, from the Mitchell Sch providing education for local ranch families to the Two Tree Mine located near the North Fork Two Tree Creek.

A network of springs and wells, such as Chuffey Spring and Buck Spring Creek, highlight the importance of water management in this arid environment. The map's detailed fencing lines and land section boundaries reflect the established agricultural divisions of the mid-20th century. Named landmarks like Doonan Gulch and Dutchman Creek offer specific touchpoints for genealogists and local historians tracing the physical history of this corner of Montana.
