About this map

Sonnette sits at the junction of 10 Mile Rd and Sonnette Rd in a landscape defined by the winding course of Pumpkin Creek. This area of Powder River County illustrates the sparse settlement patterns typical of southeastern Montana, where cattle ranching and resource extraction dominate the local economy. The terrain is marked by distinct drainage features like Doonan Gulch and Skinner Gulch, while several smaller waterways including Basin Creek, Reservoir Creek, and Dutchman Creek feed into the primary creek system.

Industrial activity is evident at the Two Tree Mine, located in the northeastern section of the map near Two Tree Creek and North Fork Two Tree Creek. Natural water sources such as Chuffey Spring and seasonal runs like Sugar Run provide critical hydration for livestock and wildlife in this semi-arid environment. The road network remains minimal, serving as the primary connectors between isolated ranching outposts and larger regional hubs.
