Hemet has a lake story full of fossils

Western Science Center in Hemet connects Diamond Valley Lake to Ice Age fossils, local archaeology, and the museum work that grew out of the reservoir dig.

Hemet has a big water story, but it also has a fossil story hiding right beside it. Western Science Center sits near Diamond Valley Lake and keeps the lake project from feeling like only a reservoir on a map.

When Diamond Valley Lake was excavated, the work uncovered a huge record of ancient life and human history from the region. Western Science Center’s exhibits let visitors meet that story in a hands-on way, including the museum’s well-known mastodon, Max.

The museum is also a working collections place. Its collection pages list over one million preserved specimens, with the Diamond Valley Lake project forming the core of its gallery exhibits. That gives Hemet a rare local doorway into Ice Age animals, archaeology, water planning, and Inland Empire science all at once.

For a visit, look up hours and exhibit details first. Then give yourself time to connect the dots: the lake, the valley, the museum building, and the older world under today’s neighborhoods.
