New Boston and the eastern banks of the Mississippi River anchor this landscape, where the river's dynamic hydrology is evidenced by features like Corsepius Island and Ziegler Slough. The Port Louisa National Wildlife Refuge occupies the southwestern bottomlands, crisscrossed by the Keithsburg Levee Trl and Spring Slough Trl. This area represents a complex riparian ecosystem where Pope Creek and the Edwards River converge toward the great river.
