Descripción del sitio
| Moraine View State Recreation Area is located atop a moraine, a low, rolling ridge located where a vanished ice sheet dumped ground rock and till while melting. Moraines are common post-glacial geological features, and can be found throughout the U.S. Midwest. This moraine was produced by the Wisconsin glaciation, about 70,000 to 10,000 years before present.
