1984 Map of Laundry Hill

About this map

Laundry Hill and the high plains of Newberry Flat define this landscape in north-central Montana, where water management is central to the local geography. The map reveals a sophisticated network of small-scale irrigation and stock water sources, including Trapper Reservoir, Mail Reservoir, and Newberry Flat Reservoir. These features, alongside named springs such as Laundry Spring and Kummerfort Spring, indicate the vital importance of reliable water for ranching and homesteading in the Missouri River drainage basin. The intricate drainage patterns of Eagle Creek, Lime Creek, and Bear Creek cut through the terrain, illustrating the seasonal flow and erosion that shape this part of Valley County. For those tracing regional land use, the placement of family-named water features like Ada Reservoir and Anna Reservoir offers clues to early 20th-century settlement patterns in this prairie environment.
