The Southern Pacific railroad and the Pacific Highway define the industrial corridor through the Umpqua River valley during the mid-1950s. This survey focuses on the rugged timber and mining country of southern Douglas County, where the settlement of Riddle serves as a key hub for rail activity and local commerce. High above the valley floor, the Nickel Mine on Nickel Mtn indicates the area's significant mineral importance, complemented by more isolated operations like the Serena Lodge Mine and Gold Bluff Mine.
