Lake Mille Lacs is a massive 200 square mile lake just two hours north of the twin cities. In many ways it is the center of the iconic Minnesota ice fishing culture. Because the lake is so large, it cannot just smoothly freeze over. Instead as the ice forms it expands and builds pressure and the ice must somehow release that pressure. The results are dramatic, jagged ridges of ice called pressure ridge, raising large chunks of ice 4-5 feet into the air. I loved the range of abstract shapes these chucks of ice form, loosing any sense of scale when photographed closely. Keep an eye here on my blog as I'll continue to post more photos from the trip.
