Crissy Field Marsh

Crissy Field Marsh is defined by its brackish water where tidal flow from the bay meets fresh runoff, creating a habitat for native plants and shorebirds that were largely absent from this site for over a century. This area was once part of an expansive salt marsh used for hunting and gathering by the Ohlone people, but it was filled in with soil and rubble during the nineteenth and early twentieth centuries to make room for the nineteen-fifteen Panama-Pacific International Exposition and later for a United States Army airfield.
