2024 Map of Loony Hollow

About this map

Loony Hollow cuts through the center of this terrain where the boundary between Prairie Co and Custer Co divides the landscape. The map reveals a remote ranching and grazing environment defined by intermittent drainages and isolated water management features like Horse Reservoir and Archdale Reservoir. These catchments, essential for livestock in this arid portion of eastern Montana, are fed by systems such as Whitney Creek and Ash Creek. The name Shoemaker appears as a key point of human presence in an otherwise sparsely populated area, while the larger drainage of O'Fallon Creek meanders through the northeast corner. This 2024 survey documents a landscape of high plains topography where the Public Land Survey System grid, including t10n r54e and t9n r54e, continues to provide the primary structure for land ownership and movement.
