Housed in a former horse stable the U.S. Army built for the cavalry in 1914, it's a researcher's delight, with five million documents, photos, oral histories, and maps. Our guided tour will explore the resources and riches of The Presidio's history.

The San Francisco Bay Area is one of the most ecologically diverse—and most transformed—regions on Earth. In his new book, San Francisco Bay Area: An Environmental History, David D. Schmidt traces how natural forces and human choices have shaped the landscape over thousands of years. Join us for a special talk and book signing with the author.

Join your member community for a day on Hawk Hill, at the height of raptor season! The GGRO was formed in the early 1980s to track the Golden Gate Migration, an annual flight of tens of thousands of hawks, eagles, falcons, and vultures, birds collectively called "raptors". With the help of over 150 volunteer community scientists each year, we conduct long term studies of the seasonal movements of raptors along the Pacific Coast, to inspire the preservation of California raptor populations. Hear about our work, talk to our scientists, and explore the iconic Hawk Hill!

Join your member community for a walk through the Lost Cemetery of Lincoln Park with former NPS ranger and historian John Martini. Few people realize that today’s Lincoln Park Golf Course was once “City Cemetery,” the final resting place for tens of thousands of San Francisco's dead. The non-strenuous walk starts at the corner 34th Ave and Clement Street, proceeds along gentle uphill paths and across some stretches of lawn before ending at the Palace of the Legion of Honor.
