1997 Map of Long X Divide

About this map

Little Missouri River serpentines through the heart of this North Dakota badlands landscape, defining the northern reaches of Theodore Roosevelt National Park (North Unit). This 1997 revision captures a transition in land management and recreation, where cattle ranching interests like the T Tarnavsky Ranch and C Lange Ranch neighbor the expansive Little Missouri National Grassland. The terrain is dominated by the prominent Long X Divide, a high ridge that separates drainage patterns toward the river and its tributaries such as Corral Creek. For those tracing historical movement through the Missouri Plateau, the map highlights the intersection of working ranch roads with established recreation routes, including the Maah Daah Hey Trail and the namesake Long X Trail. Evidence of federal oversight and environmental monitoring is found at the Park Ranger Station and the riverside Gaging Station near the park boundary.
