2011 Map of Swan Valley

About this map

The Snake River carves through this eastern Idaho landscape, defining the character of the small mountain communities of Swan Valley and Irwin. This 2011 survey documents the valley's settlement patterns, where roads like Stoltenberg Ln and Rainey Creek Rd follow the natural contours created by the river's path and its many tributaries, including Rainey Creek and Oakden Creek. The map shows a clear division between the agricultural and residential flats of the valley floor and the dramatic, deeply incised terrain of the surrounding mountains, which are punctuated by dozens of named canyons like Horse Canyon and Rocky Canyon.
