My wife and I often walk the roads and trails of the campground that is near to us. It's a US Corp of Engineers campground next to a large dam. Yesterdays walk we heard the lake moaning and pinging. The sounds were awesome. We also saw the designs below in the thin lake ice near the shoreline. What do you suppose they are? There were dozens, maybe hundreds, of these designs.
