About this map

Sonnette sits at a remote road junction in the high country of Powder River County, serving as the primary landmark in a landscape defined by an intricate network of drainages. The area's geography is shaped by Pumpkin Cr, which is fed by numerous seasonal tributaries including Basin Cr, Reservoir Cr, and Sheep Cr. This terrain is deeply incised by topographic features like Doonan Gulch and Skinner Gulch, illustrating the erosional patterns typical of the Montana plains.

Surface water is a vital resource here, marked by named points such as Chuffey Spring and an unnamed spring identified as 04S48E26BDB01 Spring. The local infrastructure consists of gravel and dirt routes like Ten Mile Rd and Fifteen Mile Rd, which follow the natural contours and ridges of the land. This map documents a quiet ranching landscape where the names of small creeks like Dutchman Cr and Sanders Cr delineate historical land use and property boundaries.
