Several years ago I visited Shefflers Rock Shop and geode mine at Alexandria, MO. It was a real treat talking to Mrs. Sheffler in her house. It was truly a geode museum. She could tell you anything you ever wanted to know about geodes. I found several nice geodes in her mine. My oldest grandson wants to go geode hunting so I immediately thought of Shefflers. However, I have heard the highway dept. took the rock shop and built a highway where it stood. Does anyone know if the mines are still open? I would like to have information about them if they are. I also understand geodes are found in the Keokuk, IA area and the Bedford, IN area. Can anyone give me some information about places to hunt geodes in any of these areas? Your help would be greatly appreciated.
