The oldest rocks in Kansas can be found right here in Blue Rapids. One distinct kind, Sioux Quartzite, was originally deposited as sand in riverbeds, buried, and - still later, deep underground - made extremely hard by heat and pressure. The quartzite formed over 1.5 billion years ago. Glaciers picked up pieces of these rocks from southwestern Minnesote, at the edge of the extremely ancient Canadian Shield, and brought them nearly 300 miles to northeastern Kansas.

Located on the Round Town Square in the heart of the only Blue Rapids in America, featuring information kiosks, sound bites and night time lighting, the Ice Age Monument is open 24/7.
