My dad and I would probably never have ventured across the ice on Lake Superior to the Grand Island Ice Caves if it were not for Facebook. We both spend a lot of time on Facebook looking at other Michigan photographer's work. Several people had been posting excellent photographs of the ice caves near Munising, Michigan and we knew we had to go. We called our friends Mike Schlitt, Bill Dietrich, and Wally Barkley and the five of us made the journey to Grand Island. D7000, F9 at 1/60, ISO 100, 10-20mm lens at 10mm
