Workers digging the new fourth bore of the Caldecott Tunnel are getting a once-in-a-lifetime view of one of the defining features of the East Bay: the range of hills that runs from San Pablo Bay south to Fremont.

Today, the East Bay Regional Park District is working to understand the complex relationships between native species, grazing cattle, and artificial ponds.
