Dallas City and Pontoosuc anchor the southern bank of the Mississippi River in this 2012 survey, where the river's braided channels create a complex landscape of islands like Grape Island and Peel Island. The northern reach is dominated by the Skunk River and its accompanying wetlands, including Skunk Slough and Patterson Lake. This area shows a distinct transition from the river-bottom lowlands to the elevated terrain of Jollyville Hill and The Ridge.
