Tower Rock
The Jackson County city of Grand Tower took its name from Tower Rock, a small rocky island on the Missouri side of the Mississippi River. At one time, a large crucifix was placed on the island by Catholic missionaries. The rock has long been feared by riverboat captains because of the rapid currents that swirl at its base. A navigational point for early explorers, this rock formation actually sits on the Missouri side of the Mississippi River, but its namesake community rests on River's Illinois shore. Lewis and Clark visited Tower Rock.
