Devil's Backbone is an unusual rock ridge that runs along the Mississippi River
at Grand Tower
in Jackson County
. Another unusual rock formation called Devil's Bake Oven is at the north end of the park.
Pitted with caves, the Oven once harbored river pirates until a U.S. cavalry troop drove them away in 1803. The park also was the site of an Indian massacre in the early 1800s.
The foundation walls of an old house still stand atop Devil's Bake Oven. According to legend, the ghost of a young girl who died of a broken heart, lingers among the ruins and is sometimes seen on quiet, moonlit nights.
