For more than 50 years, the Museum has provided inspirational scientific education to its students and the community. Initially, it was funded by a special grant from Project Gold Mind and the Museum's champion and department chair, R.A. Underhill, who oversaw the construction of exhibits based on the rising theme of ecology.

Three Scientists Break into a Lab logo with science beakerSierra College Natural History Museum has reimagined its beloved Lecture Series into a socially distanced format. The new SCNHM podcast, Three Scientists Break into a Lab, is now offered digitally each month.
In each episode, SCNHM Director Rachael Greve and Museum Events Chair/Chemistry Instructional Assistant, Casey Brown, will interview one additional scientist about current and relevant science news, discoveries, innovations, myths, and trends. Additionally, they will explore the biography of the guest scientist with questions on topics such as passions/interests, childhood curiosity/scientific engagement experiences, educational pursuits, publications, and vocational anecdotes.

The opinions or statements expressed in this podcast reflect only those of the participating individuals and/or featured guests/scientists, not the Sierra Joint Community College District.

Listen to Our Podcast

Be sure to visit this page and our Facebook page often to find fun learning activities you can do from home and share with others. Plus, we offer virtual tours, StoryTime Live and S.T.E.A.M. BedTime Story with our new co-host, FunGus.


With more than 16,000 specimens at the Museum, there is something to spark the curiosity of each and every visitor. Here are just a few of our exhibits: 

  • The Museum does not find it hard to get ‘ahead’. There are more than 70 taxidermy animal head mounts and 140 skulls on exhibit focusing on vertebrate species.

  • The Animals of the World exhibit spans the entire Museum. Come marvel at fauna from Europe, North America, South America, Asia, and Africa. Many of these massive animals are herbivores, but if carnivores are your favorite, we have a few of those as well. An interesting “sleuth” of omnivores can be found in the west lobby Bear exhibit.

  • The Marine Mammals gallery features aquatic favorites such as the unusual narwhal and loveable manatee, but the showstopper is our hanging 38ft California Gray Whale, the state marine mammal of California! Back on land, we have a dynamic fossil Tortoise display and a unique Hawver Cave special exhibit. Other featured Pleistocene beasts include the Mastodon and Mammoth Megafaunacases, Gomphothere excavation display, Ice Age Mammals, and a real Tarpit of Doom.

  • Natural History Rocks! Aspiring paleontologists will enjoy exploring the fossil record through our History of Life exhibit. It’s conveniently located underneath the gargantuan fossilized Ichthyosaur. Check out our trilobites, giant horseshoe crabs, and buzz saw-shaped Helicoprion shark tooth! One of California’s few dinosaurs is the Hypsilophodont; a Sierra College professor found its left hind leg! It’s in our Dinosauria gallery, where you can also see how you measure up to a long-necked Apatosaurus.

  • An impressive Entomology Compendiumincluding a California Butterfly exhibit, will have you buzzin’ for more bug fun.

  • The Mineralogy exhibit is visually stunning as it colorfully showcases many of the planet’s beautiful elements and minerals. Regional geological features, such as the Chico Formation display, warrant a tour stop. Don’t miss the Mosasaur skull fragment found right around the corner from us in Granite Bay.

  • Earthquake studies will make you tremble with excitement as you look for tremor activity on our real seismograph machine in the Weather Station exhibit.

  • Botany buffs will scream for green at our Sierra Forest exhibit. It’s a forest inside a museum case. Visitors are offered an up-close glimpse of the wildlife and botanicals found in our own backyard, the Sierra Nevada foothills. This lens into our unique ecosystem focuses on Northern California plants and animals featuring specimens from cedars to woodpeckers, creepy crawlers in subsoil habitats, owls, and coyotes. There’s even a rare wolverine, Sierra College’s mascot.

  • More native trees can be found in the updated Conifers of California display, which contains almost 30 species of cones. A fun, tactile experience can be found nearby at one of many petrified wood specimens. We left this mineralized former tree without an acrylic museum enclosure so students can touch and feel its ancient texture. 


Because the planetarium show is a “total darkness” environment, this program is offered for students in first grade and above. 

Our Museum offers astronomy shows in Sewell Hall’s planetarium for enrolled Sierra College students and select Museum events. Built in the late 1960s, this Moon Landing-era Planetarium seats 50 visitors.

The Planetarium Show lasts approximately one hour and consists of a PowerPoint presentation, celestial skies presentation, and Q & A session with an astronomer. 

NOTE: Planetarium availability varies per semester and is open to the Museum during K-12 field trips, select Free First Saturday events and during Dinosaur Day only. 

Nature Trails

Recommended for grades kindergarten and above. Please dress appropriately and stay on the trail. The Nature Trail is not wheelchair accessible. Off-road strollers may work on portions of the trail.

The Sierra College Natural History Museum serves as chief steward of the Nature Area. A shaded path winding through the foothill oak woodland and riparian forests has several miles of trails, including those across Secret Ravine Creek. The Secret Ravine Nature Trail is about ¾ mile long, but there is a branch that includes a gentler loop upslope to accommodate the possibility of off-road-style jogger strollers.

The Sierra College Nature Trail was designed and constructed by members of the Sierra College Science Club and their faculty advisors in the 1960s. As knowledge of the Nature Trail area has expanded, our trail guide has grown as well. The Sierra Foothills Nature Guide is available as a field guide to the biology and ecology of the Nature Trail. It covers 185 species accompanied by nearly 200 detailed original illustrations. It is available for purchase through the Sierra College Natural History Museum.

Museum Repository

The Museum is a repository for many federally permitted specimens including the Bureau of Land Management (through the U.S. Department of the Interior) and Forest Service (U.S. Department of Agriculture).

What is a Repository?

A repository is a place where things may be put for safekeeping or exhibition. The Museum is a secure and organized academic institution that does just that. We keep specimens found on federal lands on behalf of the U.S. government. We don’t “own” these fossils, but rather the Museum (or other Museums) and our scientists receive research permits for lands that are federally managed. We agree to keep important found materials and associated records protected and preserved on behalf of the government agency. In turn, we get to use the specimens for research or exhibition.

  • a guide through the tour reservation process
  • how to expedite the logistics of your visit to the Museum
