Pete Lien & Sons began as a small rock quarry operation, located on the foothills of the Black Hills, near Rapid City SD. The company was founded by Pete Lien and his two sons, Chuck and Bruce, in 1944. While the company owed its early success to business generated by nearby Rapid City Army Air Base and later to the building of the interstate highway system, it has grown through the careful acquisition of reserves and existing companies into a privately held, multi-million dollar corporation with holdings throughout an eight-state region. Through the 60-year history of the company, the Lien s core business has been mining, primarily limestone. The original quarry that Pete bought from his supplier has been mined and reclaimed. The company has purchased additional reserves and currently has active mines in northern Colorado, western South Dakota, and eastern Wyoming. The mined product supplies the company s lime and concrete plants, local road contractors and local homeowners.
