About this map

The Snake River carves through this Idaho landscape, defining the character of Glenns Ferry and Hammett in the early 1950s. This survey records a critical corridor of migration and transport, featuring the historic Three Island Crossing and the Oregon Short Line (Union Pacific) Railroad as it follows the river's path. The map details the infrastructure of a high-desert agricultural economy, including the Main Canal, a Siphon, and several Gravel Pits.

Evidence of earlier eras persists in labels for the Medbury Ferry (Aband) and the Main Trail. Remote outposts and family-named locations such as McGinness Ranch, Simpkins Spr, and Wilson Well (Dry) provide essential data points for local historians and genealogists. From the heights of Grindstone Butte to the depths of Pot Hole Canyon, the map captures the transition of the land from open range to a managed river valley.
