About the Western Science Center

Come share the excitement at this state-of-the-art museum complex!

Located off Domenigoni Parkway by Diamond Valley Lake, Western Science Center is home to a fascinating array of archaeological artifacts and Pleistocene Ice Age fossils that were unearthed at Diamond Valley Lake.

In the gallery you’ll meet “Max”, the largest mastodon found in the Western United States at the time of discovery, as well as “Xena”, a teenage Colombian mammoth. Let your imagination run wild as you walk on tempered glass, which houses “Little Stevie,” a large mastodon installed beneath the museum floor to re-create the actual dig site.

The museum campus provides excellent facilities for the research, curation, and presentation of the nearly 1,000,000 specimens discovered during the development of the Diamond Valley Lake in Hemet, California.

Scientists, researchers, students and the general public have an unparalleled opportunity to interact with and to understand the magnificent creatures and resourceful people who inhabited the Diamond and Domenigoni Valleys from the distant Ice Age past through today. There are plenty of hands on activities including a “make your own fossil” station.

Come early and take a walking tour through our native plant garden, and leave enough time to visit the museum store to pick up a unique item.
