Happy #FossilFriday! We are diving into Minnesota's rich geological history with a glimpse at some remarkable finds: 1. Cretaceous fossil ammonites in shale 2. Ordovician bedrock gastropod shells 3. Cretaceous bedrock shark tooth 4. Paleoproterozoic bedrock stromatolites

We had so much fun at Laura Jeffrey Academy! 5th and 6th grade scholars analyzed data to create their own geologic maps of Minnesota. They also discovered how to use dilute hydrochloric acid to identify certain rocks! Laura Jeffrey Academy #LJARocks

Today kicked off a unique start for our new sediment mixer at the Minnesota Geological Survey! Intended to be used for breaking down sediment samples for texture and compositional analysis, we first had to test its capabilities in a lighter, more flavorful context—milkshakes!

The Minnesota Geological Survey will be at the Minnesota State Fair this Thursday (8/22), at the UMN building! Come dive into Minnesota’s geology with our maps, explore fascinating rocks, chat with our geologists, and snag some free stickers and handouts!

We had a great time at the #MinnesotaStateFair last week! Our rock samples were a hit. See you at the fair next year!
