2011 Map of Lake Mason NE

About this map

Devils Basin sits at the heart of this central Montana landscape, where the seasonal waters of North Willow Creek and Crooked Creek carve paths through the arid terrain. The map documents a sparsely populated ranching and grazing region in Petroleum County as it appeared in the early 21st century. The sparse road network, including Winnett Rd and Alec Roy Rd, reflects a landscape defined by large landholdings and significant distances between improvements. Small-scale water management is evident at the Ivy Number 3 Dam, a common feature in this part of the state where capturing runoff from drainages like Little Wall Creek is essential for livestock. This survey provides a clear look at the topographic character and drainage patterns of the northern plains, illustrating how geographic features and ranch roads dictate the layout of this remote territory.
