The Berkeley Hills run up and down the eastern edge of the San Francisco Bay. Thirty miles long, they climb steeply off the bay’s alluvial mudflats, rising in some places to almost 2,000 feet, and they separate Alameda County’s urban cities from Contra Costa County’s low-rise suburbs. The coastal range is tall enough and long enough to affect the weather. San Francisco’s famous fog is often blocked by the Berkeley Hills, and there are many days when cities in the inner bay are socked in while communities just five miles east bask in brilliant sunshine.
