This mill site was established in 1808 when John Unthank built a gristmill along Anderson's Fork. The natural waterfall provided an ideal location for a mill. This particular mill was built in 1912 by William Oscar Beam, where Unthank's Mill stood. A dam was built over the waterfall to create a millpond, which helped turn the waterwheel that was located in the basement. The mill was converted to electric power in the 1930's. It was capable of storing 20,000 bushels of grain. Today, William's grandchildren, Maynard and Malcolm Beam, own the mill.
