2017 Map of O'Brien Hill

About this map

O'Brien Hill rises as the central topographic landmark in this high-plains landscape where Wheatland, Golden Valley, and Stillwater counties meet. The drainage pattern is defined by several seasonal waterways, including Fish Cr and Rock Cr, which carve through the undulating terrain. This 2017 survey reveals a strictly rural infrastructure dominated by ranch roads and access routes like Rock Creek Rd and S Barber Rd. The grid of the Public Land Survey System remains the primary organizing principle for the region, with the transition between t6n r18e and t5n r18e marking the steady progression of the interior west's land management history. Aside from the occasional track like Windy Ridge Trl, the area remains largely undeveloped, preserving a sparse settlement pattern focused on water sources such as Simmons Cr and Van Winkle Cr.
