Leesburg anchors this 1951 survey of the Salmon River Mountains, illustrating a rugged landscape defined by its mining heritage and high-elevation ranching. The map details a period of transition for the region’s mineral industry, marking several significant operations as inactive, including the Haidee Mine, Italian Mine, and Ringbone Cayuse Mine. These sites, along with the Jureano Placer Diggings, trace the gold and cobalt extraction that shaped the local economy from the late 19th century through the mid-20th century.
