San Francisco, California, USA
I’m so excited to be heading to San Francisco today to co-host an #InstaMeet with HERE. The theme of our event is “The View From Above” and we’ll be checking out some of the coolest views throughout the city - from both elevated overlooks and from the air! One of the places I hope we spot are the colorful salt ponds of San Francisco Bay, seen here in this Overview.
A recent figure estimates that 80% of the San Francisco Bay wetlands area - approximately 16,500 acres - have been developed for salt mining. The ponds get their particular, vibrant colors from the micro-algae that live there and the species' tolerance to salinity. Areas that have a bright red hue are caused by the algae Dunaliella, which thrives in water with extremely high salt content. For a sense of scale, this Overview shows approximately one half of a square mile.
