1966 Map of Monument Lake

About this map

Monument Lake sits at the center of this Sweetwater County landscape, surrounded by the high-desert basins of south-central Wyoming. The map depicts a territory largely defined by water management and mineral exploration, featuring the Fivemile Ditch cutting across the southern terrain. Human activity is sparse but specific, with isolated homesteads like Larsens Ranch and the Hadsell Place providing rare points of habitation in an otherwise open range. Industrial development is marked by several Well sites and a Drill Hole, alongside a long Pipeline that traverses the northern and southern sections. These features reflect the mid-century infrastructure required to support ranching and resource extraction in an arid environment where water and energy were the primary drivers of settlement.
