Just outside of Banff National Park in Alberta, Canada there is a man-made lake called Abraham Lake. While it's not exactly on the beaten path, it is fairly well known to photographers and people who enjoy the outdoors mixed with a little science. Every winter, the lake freezes and locks in bubbles of methane caused by bacteria breaking down organic matter at the bottom of the lake. In this shot, you will see some medium sized bubbles but literally tens of thousands of little methane bubbles that froze in place as they adhered to the plant life just below the surface. When I saw this particular area it seemed as if I was walking on surface of a shiny blue marble, hence the name. The temperature was a balmy 3 degrees Fahrenheit but it was so much fun exploring all of the shapes and textures embedded in the lake that I didn't even notice.
