MUSCATINE, Iowa — Located 10 miles east of Muscatine, Iowa is Wild Cat Den State Park. One featured attraction is the Pine Creek Grist Mill, constructed in 1848.
The mill has used both water power from the creek and a steam engine. It's a place where grain is ground into animal feed or flour.
As of 2020, it's being restored into its original condition and is grinding corn for the first time in 75 years.
It is thought to be the oldest working mill between the Mississippi River and the Rocky Mountains.
