Lightscape / Night Sky
Darkness is a valuable resource for visitors, and critical to the welfare of the park’s wildlife. High points in open areas within the park provide excellent opportunities to view the night sky. In particular, such areas that have little or no artificial lighting are sought by visitors to practice amateur astronomy close to home. Wildlife habitat is more valuable when unimpaired by artificial light. While high open areas in the park may provide opportunities to view the night sky, most of these locations are subject to light pollution from the surrounding Bay Area. Lighting within and adjacent to the park also reduce the darkness of the night sky. Wildlife habitat is impaired by artificial lighting.
The park is addressing protection of natural lightscapes within the General Management Planning process, and is taking steps to reduce light pollution within the park.
Did You Know?
One of the oldest tidal gauges in the country at Crissy Field shows 8 inches of sea level rise over the past 100 years (a rate 2 to 10 times higher than the previous 5000 years). We could see 2 to 3 more rise in the next 100 years.
