Check any map of Golden Gate Park. Near the Conservatory of Flowers is the “Lily Pond.” But what exactly is the Lily Pond?
Here’s some recent photos.
What the photos don’t capture is that there’s water under the green slime. Aside from a few ducks treading water, you might not even notice there’s water. It looks like a slime pit.
But what is that slime? According to the Chronicle, it’s an infestation of duckweed that took over the pond in 2010.
