The Kennedy Wheels, protected by corrugated steel sheds, operated with few interruptions 24-hours a day, from 1914 until the U.S. Government closed the mine in 1942. Soon after, when the price of scrap metal soared, the wheels sheds were dismantled revealing the wheels to the world and the elements for the first time in 28 years.
They soon became a Mother Lode mining tourist attraction and were probably the most photographed relic of the quartz mining era in California. They also became part of the (City of) Jackson Wheels Park.
