This is an algae filled pool of water located in Stanley Park in Vancouver. Diane and I were wandering along and noticed that some of the water had some neat patterns. In places, it looked like the sand had a cool colour -- but later discovered that it was algae! Here there was more algae which gave it much more of a green hue. This shot includes shadows of Diane (left), me (left center), and some grass (right). If you look carefully, you can also see the reflection of the tree leaves and the sky on the surface of the water.
