High Quality Content by WIKIPEDIA articles! Crissy Field is a former airfield, now a part of the Golden Gate National Parks Conservancy in San Francisco, California, United States. Historically a part of the Presidio of San Francisco, Crissy Field was closed as an airfield and eventually the National Park Service took control over it. While maintained by the United States Army, Crissy Field was heavily affected by the military`s dumping of hazardous materials. In 1997 the park service began to cleanup the area and 2001 the Crissy Field Center opened to the public.
