A large pile of what appears to be finely ground up limestone impregnated with lots of asbestos fibers is located at the base of the mill along the edge of Lacey Forks Creek. The asbestos appears as horizontal veins in layers of limestone. The mill, besides grinding up the limestone to remove the asbestos fibers, also sorted the fibers by length shipping out the more valuable long fibers and dumping the shorter ones in this pile. During periods of higher asbestos prices like during WWII, this refuse was sometimes re-processed at older millsites to recover the shorter fibers. But this mill operated from 1952 to 1961 and the shorter fiber debris was left behind.
