There is just something about the clear, translucent ice that fascinates me. The way it catches and scatters the light. Here are a few more examples from the Iceland PODAS. The first two images are taken shortly before sunset, and the low angle of the sun really makes the clear ice shine. The ice only stays clear for a few hours. As soon as it is exposed to warm air and sunlight the ice will become opaque and appear white due to a steadily growing number of small cracks. You can see this in the third image. Eventually the chunk of ice will break apart, turn over and expose a new portion of clear ice.
