Western Science Center

The Western Science Center, formerly the Western Center for Archaeology & Paleontology, is a museum located near Diamond Valley Lake in Hemet, California. The WSC is home to a large collection of Native American artifacts and Ice Age fossils that were unearthed at Diamond Valley Lake, including "Max", the largest mastodon found in the western United States, and "Xena", a Columbian mammoth, as well as dinosaur fossils recovered from New Mexico.

Opened in 2006, the museum has been designed to provide world-class facilities for the research, curation, and presentation of the nearly one million specimens discovered during the development of Diamond Valley Lake in Hemet.
