Ketchen Land Company owns a 2,000 acre tract in eastern Tennessee containing reserves of  between 75-150 million tons of  high-grade silica sandstone. The high silica content and low level of contaminants make this sand suitable for multiple uses including the production of glass, fracking sand, and ground silica flour. The white color of both the sandstone and the sand make these reserves perfect for golf course and play sand as well.
