Crissy Field is a 130-acre section of the Golden Gate National Recreation Area in San Francisco operated by the National Park Service (NPS) since 1994.
The area came under the control of the U.S. Army in 1846. They used the former wetlands first as a dump, then, when filled-in, as a site for seaplane operations.
The first successful dawn-to-dusk (all in daytime) transcontinental flight took off from Mitchel Field on Long Island in New York, and landed at Crissy Field in June of 1924.
The area was originally a salt marsh and estuary, used for harvesting fish and shellfish by the Ohlone people, and there are significant shell middens in the area.
