Presidio Creek Geek Hike

Some creeks are so grand. Some are pipsqueak. Lobos Creek is the only major surface creek left in San Francisco. It's big, supplying almost all the water to Presidio buildings with still enough left to gush to the ocean. Creeks help us understand what leaky San Francisco hillsides were like before development. We'll see a major natural lake that supplies the creek's headwaters. We'll even dig into groundwater studies from the nineteenth century. Highlights include drinking water out-take, sewer culvert that isn't a sewer, Chinese themed mansion, Baker Beach, Coyote Gulch, hidden graveyard, invaded jungle, historic community garden, native plant nursery, redwood grove, stone bridge and Mountain Lake. Come celebrate San Francisco's spring-laced geography with this major water geek-out!
