If you come North to photograph the world's largest fresh water lake in the winter, safety must be in the forefront, ahead of your equipment and any other artistic consideration that would be initially deployed under less arduous and dangerous circumstances. The ice flows, caves, and seemingly frozen plains are never to be trusted without careful consideration. Appropriate clothing, including snowshoes with crampons or ice cleats are mandatory, as is appropriate layered clothing. If working alone, let someone know your location and time at which they can notify authorities if you have not checked in. While it may sound a bit paranoid, we lose tourists, seasoned ice fisherman, snowmobilers, and even experienced guides each winter. This lake has the earned reputation it deserves. Your best bet for safety is to know the shoreline you are working on during the summer and fall and stay on what would normally be a shoreline or shallow area.
In the depth of winter I finally learned that there was in me an invincible summer. ~Albert Camus, Lyrical and Critical Essays
