Please add profiles of those who were born, lived or died in Monona County, Iowa.
The area around present-day Onawa was a stopping point in 1804 for Meriwether Lewis and William Clark during their exploration of the newly obtained Louisiana Purchase. Many years later, that site was memorialized as the Lewis and Clark State Park.
Monona County was formed in 1851. It was perhaps named for an Indian word meaning "beautiful valley."
