Special Event Video! Docent Dick Gehrer takes Bay Nature readers on a tour of Sierra Azul Open Space Preserve on March 21, 2009. We get a chance to see beautiful spring wildflowers, and we learn a bit about the mysterious concrete monolith atop Mount Umunhum. This event was part of our hikes program.
