Backbone State Park

Backbone State Park is Iowa's oldest state park and is arguably the world's only state park named after a backbone.

According to Wikipedia, the Backbone State Park area "was left unglaciated during the last Ice Age." I didn't know that "unglaciated" was a word. But I like it. It's also nice to know that I have something in common with the Backbone State Park area.
