One of the largest and finest collections of rocks, minerals and fossils in the Midwest.

Visiting the museum
Dr. William Hammer
Visitors are greeted by a 22-foot-long skeleton of a Cryolophosaurus, a large carnivorous dinosaur discovered in Antarctica in 1991 by Dr. William Hammer.

The museum, named after Dr. Fritiof Fryxell, began in the late 1880s with a modest natural history collection. Today it has more than 1,500 rock, mineral, and fossil specimens and a fluorescent mineral display.

Admission is free.
