About this map

Johannson Coulee and Fifteenmile Coulee carve through the high plains of Toole County in this 2020 record of north-central Montana. The landscape is defined by its drainage network, where Ninemile Coulee and Black Coulee move water across a sparsely populated agricultural expanse. These features illustrate the natural topography that dictated the placement of local thoroughfares like Gus Blaze Rd and Johannsen Rd.

Evidence of historical water sources is found at 36N02E07C Spring near the eastern margin, while Black Butte provides a rare point of elevation in the southeast. This survey preserves the modern township and range grid, showing how the land remains partitioned into large sections. The presence of Miners Coulee in the northeast hints at the region's history of extraction, even as the primary character remains that of an open, prairie-tilled interior drained by Willow Cr and Flat Coulee.
