About this map

Sadie Coulee and its surrounding drainage systems define this section of McCone County, where the high plains are deeply incised by a network of seasonal watercourses. The landscape is marked by numerous named draws, such as Dead Man Coulee, Williams Coulee, and Rosie Coulee, which channel runoff toward more significant tributaries like Prairie Elk Cr. This terrain reflects the traditional ranching and dry-land farming patterns of Eastern Montana, where water management is critical for sustainability.

Evidence of human occupancy and infrastructure is found in the south, where Gass Reservoir sits along Gass Rd. For genealogists and local historians, the inclusion of Ervine Cem in the southeastern corner provides a specific point of interest for family research. The map documents the persistent township and range grid system across this undulating territory, notably through t24n r46e and adjacent boundaries.
