90% of land in Iowa is privately owned (or so I am told). Today I found a piece that isn't. It is a bend in the river where the army core of engineers engage in controlling the river via a dam. Next to the dam is an area know as the Devonian Fossil Gorge. It is an ocean floor fossil bed similar to what you find at the top of the Grand Canyon. The gorge was created/exposed by floods in 1993 and 2008 that washed the top soil away.
