2023 Map of Swan Valley

About this map

The Snake River carves through this corner of Bonneville County, defining the corridor where the settlements of Swan Valley and Irwin are situated. This modern survey reflects a landscape where public lands of the Targhee National Forest and Caribou National Forest meet the agricultural and residential life of the river bottom. The map traces the transition from the irrigated fields of Flatiron to the high elevations of the Caribou Range and Ross Peak. Local aviation is represented by Huskey Airport, while genealogy interests are served by the location of the Swan Valley Cem and the Burton-Irwin Cem. The intricate network of canyons, such as Oakden Canyon and Rainey Creek, illustrates the complex drainage system feeding into the main river valley, a topography that has long dictated the placement of roads like Pine Creek Rd and Ranger Station Rd.
