Presidio Creek Geek Hike

 

Some creeks are so grand. Some are pipsqueak.

Mountain Lake in the 1930s. Its west shore was filled in to accommodate Highway 1 bursting out of a tunnel.

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. Dragonfly creek and lots of unnamed creeks we’ll explore are cool, too. They 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: drinking water out-take, sewer culvert that isn’t a sewer, treatment plant, Chinese themed mansion, Baker Beach, Coyote Gulch, hidden graveyard, invaded jungle, base commander’s mansion, historic community garden, native plant nursery, redwood grove, stone bridge, twin palms, ridge trail, leaky cliffs by the Golden Gate, rehabbed nature, invasive vines, dune boardwalks, Mountain Lake.

Come celebrate San Francisco’s spring-laced geography with this major water geek-out!
