1947 Map of Glenns Ferry

About this map

The Snake River dominates this mid-century landscape, carving through the high desert of Elmore County where the historic southern route of the Oregon Trail followed its banks. This survey captures Glenns Ferry as a vital river crossing and railroad hub, with the Union Pacific line running parallel to the water. The complex network of the Main Siphon Canal, Ditch segments, and Flumes illustrates the intensive irrigation infrastructure required to sustain agriculture in this arid region. Notably, the map marks Three Island Crossing, a famous ford for westward pioneers, and includes an Historic Marker and a nearby Cem. The rugged southern terrain is defined by the steep descents of Deadman Canyon leading toward Deadman Flat, where the Deadman Falls Dam sits at a sharp bend in the drainage, while the northern uplands are punctuated by the prominent King Hill.
