Next time you fly to the City by the Bay, make sure to ask for a window seat. You'll be amazed as you peer out from your bird's eye view. On a clear day, you can see massive rainbow salt flats of San Francisco Bay painting the landscape.
In fact, they're so big that NASA can even see them from outer space!
Bright fuchsia pinks, pumpkin orange, and green waters run together like oil paints.
You're probably wondering how they got there.
While they might look natural, the ponds are actually the result of man-made salt ponds used to extract and harvest salt from the Bay's water.
According to NASA, more than eighty percent of San Francisco's wetlands have been sectioned off for salt mining, which the city has supported since 1854.
Cargill, a local company, has operated the wetlands since 1978 and has sold thousands of acres of land back to California and the Don Edwards National Wildlife Refuge.
NASA's Earth Observatory reported that these coordinated efforts provide a "valuable habitat for birds, fish, and other wildlife. The wetlands will contribute to better water quality and flood control in the bay, and open up more coastline for public enjoyment."
As Bay water is slowly introduced into the wetlands, the vivid color of the salt ponds will change.
Since this is likely a long-term project, you can still take time to catch an amazing view of this San Francisco wonder.
