The recent freeze-thaw-freeze-thaw-freeze cycle has created some interesting ice formations. I spent the past few days photographing the ice in Mackinaw City and Petoskey.
On Saturday, my daughter and I drove up to Mackinaw City to capture the blue ice, stacked high along the shore. The color of the ice was a seemingly unnatural blue. My daughter wanted to know more, so she used her iPhone to research the colored ice. What she discovered is that it is a lack of bubbles in the ice that cause the coloring. Without the scattering effect of air bubbles, light can penetrate ice undisturbed. When the light is absorbed, it reflects light at the blue end of the spectrum, giving the ice its coloring.
On Monday afternoon I was driving home from work and noticed the unusual geometry of the ice near the Petoskey piers. Nearest the shore, was large hunks of ice frozen in place. Further out was jagged ice, as if a single ice sheet was shattered into a million tiny pieces and then refrozen almost instantly (it appears like rain is falling on the lake, but it is in fact those tiny jagged pieces of ice). What inspired me was the way the ice was segmented in a gentle arch around the harbor.
