The polar vortex got a lot of press over the past few weeks, and for good reason. It was cold. Not the coldest ever along Lake Michigan, but still, respectably cold. The result has been more ice coverage over the big lake than has been seen in years. From the shore, it looks like an infinite expanse of ice. Here, the late afternoon sun streams across the frozen waters along the shore of the Door Peninsula, the shadows cast by the lowering sun accentuating both the rocky shore and the textures of the snow covered ice.
