2011 Map of Loony Hollow

About this map

O'Fallon Creek and its southern tributaries, Whitney Creek and Ash Creek, define this Prairie County landscape in the early twenty-first century. The map documents a sparsely populated ranching or agricultural environment where water management is critical, as evidenced by Marshall Dam, Gray Number 1 Dam, and the Horse Reservoir. Small rural locales like Loony Hollow and Shoemaker are connected by a network of local roads and 4WD tracks that navigate the drainage basins. Transportation infrastructure is represented by the railroad at Lacomb Siding in the northeast, while the presence of the Archdale Reservoir further highlights the systematic collection of seasonal runoff in this part of Montana.
