1961 Map of Rex Lake

About this map

Centennial Valley and the surrounding high-altitude terrain define this 1961 survey, where the Union Pacific railroad cuts across a landscape dominated by ranching and resource extraction. The map captures a moment when the Rex Lake Oil Field was an active industrial presence near Rex Lake, marked by several Oil Wells and a Water Tank that speak to the local petroleum economy. In the southern portion of the sheet, the Little Laramie River winds through the valley, supported by an intricate network of irrigation systems including the North Fork Ditch No 2, Adams Ditch, and Dominic Ditch. The transition from the valley floor to the timbered slopes of Sheep Mountain and the Medicine Bow National Forest is clear, with family-named landmarks like Ward Gulch and Bald Mtn providing essential context for those tracing local land use and 20th-century Wyoming history.
