The sand dunes of the Indiana Dunes National Lakeshore seen from far offshore, beyond the shelf ice that lines the beach. The space between the mounds of ice in the foreground, and the 125 foot tall sand dunes in the distance is Lake Michigan - frozen solid with shelf ice, and drift ice. This winter, over 60 percent of Lake Michigan is covered in ice, and liquid water cannot be seen anywhere between shore and the horizon.
If you view this image full size, the ice along the shore is clearly visible; mounded up by waves crashing in to the shore several weeks ago. This provides an example of the extent of the ice.
While this ice appear solid, it's actually floating on the surface of the lake, and moving slowly. Extremely dangerous to walk on, the temptation is far too great for the people who ignore the danger signs and venture out onto the ice - a potentially deadly undertaking.
I was in a safe location while taking this photo, not on the shelf ice.
