Fryxell Geology Museum

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. 

School field trips generally are scheduled between 9 a.m.-2 p.m. Monday-Friday during the academic year. For specific times and dates for field trips, email or call Elizabeth Plumb, 309-794-7318, in advance.

Spring open house May 6

Join us for an evening of stargazing and planet viewing from 8:30-10 p.m. May 6.

The Augustana College's Fryxell Geology Museum and John Deere Planetarium will be open for free indoor and outdoor programs, including views through Augustana's Carl Gamble Observatory telescopes. 

In the event of cloudy skies, the indoor planetarium programs will still be offered.

There is no charge for admission.

This year’s open house will feature Jupiter, the solar system’s largest planet. Our telescopes will reveal Jupiter’s cloud patterns and moons as well as the mountains and craters of the Earth’s moon.

Also on display will be a quarter-ton piece of the Canyon Diablo meteorite and a planetarium show with images and information on the wonders of the night sky. 

The Fryxell Geology Museum, which features one of the best collections of minerals and fossils in the Midwest, will also be open. Highlights include a wall of glowing fluorescent rocks, as well as a cast of a Tyrannosaurus rex skull and a complete 22-foot long skeleton of Cryolophosaurus, a large crested carnivorous dinosaur discovered in Antarctica.

The observing areas are unheated, so dress appropriately for the weather.
