1968 Map of Twelvemile Knoll

About this map

Emigrant Trail tracks across this high-plains landscape, marking a historic corridor of westward expansion through Sweetwater County. This late 1960s survey documents the intricate intersection of pioneer history and modern resource exploration. The map clearly identifies the (Sublette Cutoff), a critical bypass for wagons seeking to avoid the Green River crossing, etched into the terrain alongside contemporary industrial markers like Little Colorado Well No 9 and Little Colorado Well No 10. The Lincoln Sweetwater Road serves as the primary modern artery, winding through the complex topography near Twelvemile Canyon. The area around Twelvemile Knoll remains largely undeveloped, defined by sparse infrastructure such as an isolated Drill Hole, reflecting the enduring character of this arid Wyoming region.
