Digging for Geodes in Hamilton, IL

Home » Illinois » Dig for Geodes in Hamilton

Jacob’s Mine is a privately owned mine known for its geodes.  It’s open to the public year-round and rockhounds commute from other states to dig these one-of-a-kind geodes. You’ll find quite a few geodes once you locate the pay streak or band in the shale/clay.  Keep an eye out for rounded-looking nodules, those are keepers.

Digging for geodes is one of my favorite weekend activities and Jacob’s Mine doesn’t disappoint.  What makes discovering a geode so great is that you’re the first person to lay eyes on it.  Think about it, that geode formed over thousands of years ago and you found it.  That’s pretty cool!

This location is excellent for families, junior rockhounds, and old-timers.  

Keep reading below to learn more about what to bring, types of clothing to wear, and driving directions.  We even provided a direct link to the mine owner making it easy for you to schedule a dig.

Types of Geodes

While digging in the pay streak you’ll want to look for nodules among the jagged-looking rocks.  I’ve provided an example picture below to help you with identifying geodes while you dig.

Keep scrolling lower and you’ll see a 5-gallon bucket full of these amazing geodes.  This is not unusual and that’s why so many rockhounds visit this location year round.


  • Geodes – ranging in size from 4-inches in diameter up to 14-inches in diameter.  Some are solid while others are filled with Quartz crystals.  You won’t know until you break them open or saw them in half.
