Mystery Mineral Day (September 25)

Mark your calendars for the return of Mystery Mineral Day, scheduled for Saturday, September 25, 2021 in the Northwest Gallery. The always-anticipated event runs from 10:00 am to 2:00 pm.

Every year, the Museum organizes a panel of experts in the fields of rock & mineral identification, fossil study, and meteorite analysis. We bring together experts from multiple fields to inspect your “mystery” finds and tell you what you’ve found. The event is FREE with paid general admission. We encourage you to schedule an appointment. Limit 5 items ID’d per person. Capacity will be limited.


Greg Carr

Greg has prepared, loaned, donated, or conserved many impressive specimens for the museum, including “Bernie” the Thalattosaur, a large Brontothere skull, and an impressive plate of local Crinoids.

Jill Johanssen
Jill describes herself as “one of those kids who loved rocks”. For as long as she can remember she was picking up rocks, putting in her pockets, (and one up her nose), then stashing them in a large shoe box under the stairs in her father’s garage. It was a hobby Jill studied on her own and though she took some Geology in college, it was only the rock science that really had her interest. Jill attended the Gemological Institute of America (GIA) and turned her hobby into a career. Her goal is to one day teach Gemology and share her passion with others. Nothing makes her happier than seeing people of all ages get excited to learn and knowing she can help inspire rock lovers everywhere.

She develops exhibits, conserves our collection of minerals, gems, rocks, meteorites, and fossils, and promotes the museum’s mission to engage, inspire, and educate on the wonder and complexity of our Earth.
