CANCELLED: Celebrate Idaho Geology and Earth Science Week

Due to low registration this event has been cancelled.

Dig into Geology! You’ll find activities for all ages and treasures for the kiddos. Hunt for gems, explore Idaho rocks and minerals, create your own earthquake and MORE!

We have planned this event carefully, so that during this COVID surge, we can all stay safe. We are scheduling 25 people per hour between 1:00 pm & 4:00pm and requiring everyone 3 and older to wear a mask that covers the nose and mouth. The museum door will be open. Come join us for a good time!

Our gift shop will be open, so plan to come in and explore our affordable and amazing collections!
