Palisades is the word used to describe a line of lofty, steep cliffs usually seen along a river, and Mississippi Palisades, 3 miles north of Savanna in Carroll County, handsomely lives up to its name. Caves are evident as are dangerous sink holes - limestone caves that go straight down. Erosion has carved intriguing rock formations, including Indian Head, with its aquiline characteristics, and Twin Sisters, a pair of humanoid figures on the bluff tops. Wooded ravines, whose brilliant hues splash the cliffs with color each autumn, dissect the unglaciated terrain. Ferns dot the deep ravines, while in the park's northern region, leaves of the white birch ripple in the wind. Each spring and summer the valleys and slopes are dappled with the blooms of trillium, bluebell, lobelia, shooting star and yellow ladies' slipper.

Animal life, within the park and the river areas immediately adjoining it, is varied. Waterfowl and shorebirds are numerous, as are wild turkeys. Striking pileated woodpeckers make their home in the park, and depending on ice conditions, eagles feed at the river in January and February. Because so many birds migrate along the river, their lyrical songs can be heard at the Mississippi Palisades each spring and fall.
