This is so cool to see our work from SPACE. East of LA’s lights the biggest dark spot (open space) is the Cleveland National Forest. If you follow that up the photo, you can see the entire Puente-Chino Hills Wildlife Corridor. Zoom in to get a closer look.

If you are geographically challenged, find the biggest island (Catalina) by the rectangular-ish point (Palos Verdes) and the Puente-Chino Hills are northeast from there (aim to 2:00)
