Michael DeWitt took this stunning photo from Apostle Islands National Lakeshore in Wisconsin. Here’s what he had to say about it.
"In late December, a friend and I launched a canoe from the pack ice at Meyer’s Beach, gateway to the mainland sea caves in the Apostle Islands National Lakeshore. We broke skim ice and dodged ice bergs out to the caves, and we were well rewarded for our efforts. I made the image from the canoe, through a port hole as the sun set across Mawikwe Bay."
