Dig into Geodes was a huge success yesterday with approximately 350 participants cracking geodes, touring the Museum and taking a 40-minute geology hike.

Twenty-five Museum volunteers made this event run smoothly on a beautiful day. Lots of happy people!
We couldn't have done it without the help of the Idaho Museum of Mining and Geology volunteers, Old Pen staff, Idaho Humanities Council, East Boise Community Work Center and UpDog Street Food and Catering .

We'll see you all again on September 20 for more geode-cracking!

Let's Dig into Geodes and see what's inside!
10 am - 1 pm
Sunday, June 14

Join us at the Idaho Museum of Mining and Geology (IMMG), next to the Old Pen, for a fun time geode-cracking, an easy 40-minute geology hike on the nearby hillside and a Museum visit.

If you have never seen a geode cracked open with a giant pipe-cutter, you are in for an exciting moment. What Mother Nature has created is truly amazing.

Geode-cracking takes place in 6 half-hour sessions from 10 am and 1 pm outside under shade canopies on the grass of the historic Women’s Ward. Please register at your preferred time.

Take a hike before or after your session. Hikes are scheduled for between 10:30 am and noon.

Delicious hot dogs will be on sale by Updog Street Food beginning at 11 am.
