We live a few blocks from the shore of Lake Winnebago, one of the largest inland lakes in the country. As long as I can remember, it has been a ritual every spring to go down and look at the ice shoves. As the ice melts, the waves push the broken ice to shore, and it piles up almost like a snowbank. Sometimes the shoves are taller than the nearby houses. This year they're actually pretty low, but still fascinating (at least I think they are!).
Here is a picture of Henry sitting on a chunk of ice. You can see how thick the ice still is (about 15") when it shoves up on land.
Another picture of Henry in front of a larger pile. This tree root is right on the shoreline:
Interesting, or no? I think so!
