Western Science Center is home to a fascinating array of Native American artifacts and Ice Age fossils that were unearthed at Diamond Valley Lake. You'll be moved by "Max", the largest mastodon found in the Western United States, as well as "Xena", a Columbian 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.
