Sketchbook #114: Overgrown Creek

A small creek runs through the city where I live and its path is controlled by high cement walls - which is necessary for a flood-prone area. Every year it's getting cleaned with bulldozers and large crews of workers and looks very clean and urbanized. But nature is fighting and within a month water brings enough soil to start vegetation and soon it's a thriving ecosystem: ducks bring up their young there, you see squirrels and raccoons go for a walk, butterflies and hummingbirds and all kinds of insects!
