1966 Map of Swan Valley

About this map

The Snake River flows through the heart of the Swan Valley on this 1966 field-checked survey, illustrating a landscape defined by the convergence of the Targhee National Forest and the Caribou National Forest. The small agricultural and mountain settlements of Swan Valley and Irwin are the primary hubs of activity, supported by landmarks like the Ranger Station and rural structures such as the Chapel in the Valley. The terrain is deeply textured by numerous canyons, including Holland Canyon and Oakden Canyon, and high points like Ross Peak and Baldy. Local industry and land use are evidenced by the Gravel Pit near Irwin and various storage bins along the valley floor. Transportation for the era is well-documented through a network of a Jeep Trail, Pack Trail, and the Indian Creek Trail, reflecting the area's role as a gateway for forestry and recreation.
