Water, Wind & People: The forces that shaped Crissy Field

The restored salt marsh at Crissy Field is a landscape shaped by forces both natural and human. Originally part of a larger system of wetlands ringing San Francisco, the marsh and surrounding area was filled in the late 1800s and early 1900s. In 2001, a restored marsh was created by excavating a lagoon out of the artificial fill. The marsh today is a thriving ecosystem that attracts birds, fish, native plants, and a steady stream of visitors from around the world.

What many visitors may not know is that the marsh requires active maintenance to stay a marsh; transport of sand along the beach by ocean waves periodically blocks the flow of water into and out of the marsh, and the channel to the Bay must be mechanically excavated several times a year.

On this walk we will discuss how the interplay of sand, water, wind, and people shapes this landscape, explain why the marsh is not self-maintaining in its current form, and observe some of the plants and animals that reside in the marsh.
