East Bay residents have a volcano in their backyard at Sibley Volcanic Regional Preserve. Originally called Round Top Park, Sibley shares with Temescal and Tilden the distinction of being one of the East Bay Regional Park District’s original parks. The preserve was later named in honor of Robert Sibley, who helped found the District and served for 10 years on its board of directors.
