This exhibit explores the unique history of Ontario—it’s founding, transitions, people and organizations. Explore Ontario from its roots beginning with the Native Peoples and Californio Rancheros to its founding by George Chaffey. Discover why it has been called both a “Model Colony” and the “Gem of the Foothills.” The book, Ontario The Gem of the Foothills by Michael L. Rounds, traces Ontario history from the Native American era to the present day. Many historic images from the museum’s collections are published here for the first time. This interpretive history about our community is for sale in the museum store.
