2024 Map of O'Brien Hill

About this map

O'Brien Hill rises as a central topographic landmark in this high-plains landscape, where the borders of Golden Valley, Wheatland, and Stillwater counties converge. The drainage patterns of Fish Creek in the north and the meandering Rock Creek across the central and southern sections define the drainage of this ranching country. Settlement is sparse, characterized by a network of rural routes named for local families and natural features, such as Haase Rd, Miller Rd, and Rock Creek Rd. The presence of Windy Ridge Trl suggests a terrain shaped by consistent winds across the open range. This modern topographic record captures the enduring spatial organization of the Public Land Survey System, showing the section lines that continue to dictate property and road placement in this part of Montana.
