2012 Map of Arminto SW

About this map

Osborne Place and the surrounding high plains of Natrona County characterize this corner of Wyoming as it appeared in the early 21st century. The landscape is defined by its ranching heritage, with large landholdings such as Neff Ranch to the north and O'Donnel Ranch near the center of the quadrangle. These family-named landmarks are connected by a sparse network of local roads that navigate the arid terrain. Natural drainage is limited, with Poison Cr cutting through the northeast corner, providing a vital geographic marker in an otherwise expansive and open territory. This map serves as a detailed record of land use and rural infrastructure in the Arminto region, capturing the remote nature of Wyoming's ranching districts before further modern development changed the visual character of the plains.
