Mackay in Custer County, Idaho — The American West (Mountains)
Ghost Towns of Mackay, Idaho
Cliff City and White Knob were bustling mining towns established west of Mackay in the late 1800s.
After copper was discovered in the White Knob Mountains in 1879, Cliff City and White Knob sprang up to support the mines. The boomtowns were home to hundreds of miners and boasted stores, saloons, a post office, school and theater. Both town died in the early 20th century, as Mackay became the regional mining center and the copper industry waned.
