Blue Ice at Bay City

Great Lakes Drone Works captured some awesome shots from the ice on Saginaw Bay near Bay City. They write:

We made our way out to Bay City State Park to capture some images of these huge chunks of ice. At first we were hoping drone photos would be the way to go but after walking around and getting up close, it was clear that ground photography was the better option.
Blue ice occurs when weather conditions — such as a lack of high winds — allow water to freeze slowly and evenly, resulting in ice composed of large crystals (unlike snow, which is formed quickly and made up of small crystals).

When light hits these big ice crystals, it can travel deep into the structures (compare this to snow, wherein light hits a sharp edge and reflects off of it right away, resulting in blinding white). When the light travels deeper into slowly formed ice, some of the red wavelengths of sunlight — which is the longest wavelength of visible light — get absorbed into the ice structure.

The blue, which is the shortest wavelength of visible light, bounces back out, meet our eyes, and results in a deep aqua color.

Head over to their Facebook for more shots and get lots more icy goodness at the ice tag on Michigan in Pictures!
