Muir Woods National Monument is known for its towering redwoods because some old growth trees have been preserved there. But redwoods used to grow all over the San Francisco Bay Area until they were logged for their timber just after the Gold Rush. Most of what we see in places like Reinhardt Redwood Regional Park in Oakland are second growth trees, ones that have grown since that time. After the 1906 earthquake and fire was another period of intense logging. Timbermen worked their way up the coast to provide the lumber that would rebuild San Francisco. Bay Curious listener Christy Dundon wants to know just how much of our old growth forests were devestated.

Before Silicon Valley, before the Valley of Heart’s Delight, the hills south of San Jose were home to one of the world’s richest mercury mines: New Almaden. Its quicksilver powered the California Gold Rush, but today, few traces of those boom boom days remain, other than the toxic legacy still circulating in the San Francisco Bay. In today's episode we answer three listener questions about the mine and it's history.

San Francisco's Golden Gate Park is at the heart of city life. Created in 1870 when the land was mostly sand dunes, the park is now one of the crown jewels of the city by the bay and is a must-visit for anyone traveling here.

While you might not recognize the name, there’s a good chance you’ve heard the haunting, almost otherworldly sound the duduk makes. This humble shepherd’s flute wandered out of the Armenian countryside and into Hollywood, making cameos on the scores of movies and shows like The Gladiator and The Last Temptation of Christ. The duduk was even recently synthesized on both Dune soundtracks. Audiences in the Bay Area don’t get many chances to hear the instrument live — unless they’re able to catch a performance by Santa Rosa-based Khatchadour Khatchadourian -- the duduk whisperer.

After the 1906 Earthquake and Fire, thousands of San Franciscans were homeless. City leaders needed them to stay in the city to help rebuild, so they built tiny homes and set up villages in neighborhood parks. These earthquake cottages gave many people their first shot at homeownership and helped the city recover. You can still find a few of them dotted around the city if you know what to look for.

Rita Hayworth, Robin Williams, Adele — these are just a few of the huge stars that have graced the stage of Bimbo’s 365 Club over its 94 years in San Francisco. But the act the club is most famous for is Dolphina — or the “Girl in the Fishbowl.” Dolphina isn’t a person, though; she’s a character who’s been played by many different women since 1931.
