2017 Map of Flat Bottom Coulee SW

About this map

Longfork Creek and its primary drainage system define the topography of this high plains landscape in eastern Montana. This 2017 survey details the complex network of drainages that channel seasonal runoff toward the Yellowstone River valley, including the prominent E Fork Longfork Creek. The terrain is characterized by deeply incised geographic features named for early ranching or homesteading interests, such as Nelson Coulee in the northwest and Larson Coulee to the south. Centrally, the namesake Flat Bottom Coulee illustrates the characteristic erosion patterns of the region. These features, mapped within the township boundaries of t10n r38e and t9n r38e, highlight a landscape primarily shaped by natural watercourses and the Public Land Survey System rather than dense human settlement.
