2020 Map of Johnson Coulee East

About this map

Johnson Coulee and the surrounding drainage basins define this portion of McCone County, where a network of intermittent streams carves through the high plains. The landscape is characterized by the headwaters and branches of Nelson Creek, including its significant S Fork Nelson Cr, which weave through the southern sections. To the north, the terrain transitions toward Horse Cr and its tributaries, reflecting the complex erosional patterns typical of this Montana region. Local infrastructure is limited to a few arterial routes such as Horse Creek Rd and Mayberry Rd, which follow the natural contours of the land. These roads connect isolated ranching tracts, highlighting the area's enduring reliance on the drainage system for orientation and land division. The map also captures several distinct watercourses like Stony Butte Cr and Cotter Cr, tracing the hydraulic connectivity of the Missouri River watershed.
