We're headed way up north and 9 years back in time for some amazing aerial photos of ice on Lake Superior above the Keweenaw Peninsula, Whitefish Bay, Marquette and Isle Royale. The photos were taken February-April 1997 at altitudes of 600-1400 m above the lake (some as high as 3000 m) with hand-held SLP cameras using slide film. Most of the photos were taken by Mike Bohn and you can see a whole bunch of shots in the Great Lakes Ice Group Archives at Michigan Tech.
