This waterwheel, which was built in the 1800’s, drives a gristmill. The mill is still completely operational today. It is preserved and maintained as a historical monument at Cades Cove in the Great Smoky Mountains National Park. Inside the wooden building tourists can watch the antique gristmill as it grinds up kernels of corn or wheat. You can even purchase bags of cornmeal or flour ground up by that very same mill. The original owner took double advantage of this waterwheel by using it also to power a sawmill. This photograph was shot at the slow shutter speed of 3.6 seconds, thus making the wheel appear to be spinning much faster than it really was.
