Guide to the Western Science Center – Inland Empire’s Natural History Treasure
Located in Hemet, California, close to Diamond Valley Lake, the Western Science Center is a lively natural history museum that reveals the Inland Empire’s ancient past. It’s much more than just a collection of old bones. The museum features amazing fossils found during the construction of the lake in the 1990s, which were among the largest fossil discoveries in the country.
Visitors can see the famous “Pacific Mastodon,” life-sized Ice Age animals, and interactive exhibits. The Western Science Center invites families, students, and anyone curious to explore millions of years of local history. Whether you love dinosaurs or just want an affordable, educational outing, this hidden gem offers a fun and welcoming experience.
Snapshots in Time: Meet the Ice Age Giants
When you enter the main gallery, you’ll see huge mammoths and mastodons up close. The highlight is “Max,” an impressive Pacific Mastodon skeleton, along with life-size models that help you imagine what the world looked like 50,000 years ago. There’s also a recreated quarry where you can look at real mastodon bones, and interactive stations where you can make your own fossil casts.
Introducing the Pacific Mastodon — Western Science Center
These exhibits showcase the amazing variety of Ice Age animals that once lived in the Diamond Valley area, including camels, ground sloths, and saber-toothed cats. Visitors can enjoy hands-on activities that celebrate the region’s prehistoric wildlife.
Prehistoric Pathways: Dinosaurs from the Cretaceous
Check out the museum’s newest permanent exhibit, Prehistoric Pathways, which takes you through a Cretaceous forest from 80 million years ago. You’ll meet dinosaurs that Western Science Center researchers have studied, such as Dynamoterror, Invictarx, and Ornatops from New Mexico’s Menefee Formation. This area connects local Ice Age discoveries with dinosaur finds from other places.
Harley Garbani – Dinosaur Hunter
Learn about Harley Garbani, a well-known local fossil hunter whose discoveries are a key part of the museum’s collection. This special exhibit displays both original and replica fossils, including a Tyrannosaurus rex skull, and highlights his lifelong dedication to paleontology in the San Jacinto Valley.
Hall of Archaeology: From Native Americans to Settlers
Explore more recent history in the Hall of Archaeology. Find out why there are no dinosaur fossils at Diamond Valley Lake, look inside a recreated home from the 1880s, and see Native American artifacts that show thousands of years of people living in the area. This exhibit connects the region’s natural history with its cultural heritage.
Immersive Theater Experience
Be sure to visit the circular immersion theater, which has a 270-degree screen. Every half hour, you can watch two short films: Echoes of the Past, an animated film that brings giant creatures to life, and Discovery and Recovery, a documentary about the huge fossil excavation during the lake’s construction. For the best view, sit near the back.
Special Events & Rotating Exhibits
The Western Science Center is lively year-round with events such as the Inland Empire Science Festival, 60 Minute Science workshops, guest speakers, school tours, summer camps, and hands-on activities for families. Rotating exhibits and temporary displays mean there’s always something new to see. Members get free entry and discounts.
Visit Diamond Valley Lake
Most people spend 1 to 2 hours at the Western Science Center, so it’s easy to include a trip to nearby Diamond Valley Lake, the largest man-made lake in Southern California. The lake is great for fishing, boating, kayaking, hiking, and biking, especially when wildflowers bloom in spring. There’s a 1.5-mile shoreline trail near the east marina, and longer trails go around the lake. Bring a picnic and take in the scenery.
