1952 Map of Arminto SW

About this map

Isolated ranching outposts and high-plains educational landmarks dot this 1952 topographic study of Natrona County. The landscape is defined by the ephemeral Poison Creek and a network of windmills critical for livestock in this arid environment. Evidence of a changing rural structure is visible through several sites already noted as unoccupied by the early 1950s, including the Poison Creek School and the Osborne Place. Family-named landholdings like the Neff Ranch and O'Donnel Ranch anchor the local geography, while the Divide School served as a central point for the surrounding homesteads. This survey was conducted as part of the Department of the Interior's Missouri River Basin development program, documenting the terrain at a scale of 1:24,000 to assist in regional water and land management planning during the mid-century period.
