Exhibit Summary
Marin County's Great Divide


This exhibit looks at Marin County, California, from the perspective of its geography, and how that geography shaped the County's development from Sir Francis Drake to the current era. Since it was first explored, Marin County watersheds draining directly into the Pacific Ocean and Tomales Bay have typically remained less developed and rural. Conversely, eastern draining watersheds flowing into San Pablo Bay and San Francisco Bay have become far more developed and urbanized. The photographs in this exhibit show how this pattern has endured from colonial exploration to the present day.
