During the 1920s, Fruit Growers Supply Company operated six railroad logging camps in the vicinity of Martin Springs, located between McCoy Flat Reservoir to the south and Pine Creek Valley to the north.
Camp C had a unique feature not found in other logging camps. It should be duly noted that Fruit Growers valued their employees and took good care of them. In 1923, Fruit Growers built an outdoor boxing/wrestling area that seated 500 at Camp C. On June 23, 1923, the inaugural wrestling match was held between Susanville resident Bill Mohler and Paul Kinney of Omaha, Nebraska. A special train from Susanville was dispatched to Camp C to allow their mill employees to attend.
