1963 Map of Sodergreen Lake

About this map

The Laramie River winds through the southern reaches of this landscape, its waters diverted into an intricate network of irrigation channels including the Sodergreen High Line Ditch and the Pioneer Canal. This 1960s survey reveals a high-plains ranching economy defined by water rights and family holdings, with named sites such as the Sodergreen Ranch, Johnson Ranch, and Hanson Ranch dotting the terrain. The northern half is dominated by the expansive Lake Hattie Reservoir and the smaller Sodergreen Lake. To the west, the topography rises sharply into the Medicine Bow National Forest, where Sheep Mountain stands within the Sheep Mountain Federal Game Refuge. Local community life is anchored at the Harmony Sch, while the presence of the Lake Hattie Supply Canal and various ditches like Fisher Ditch illustrate the engineering required to sustain agriculture in this arid Wyoming environment.
