Lake Superior ice is always changing and is always fun to watch. Sometimes it’s dramatic and sometimes it is just frozen water. As of Thursday the official NOAA announcement was that the lake was 86% ice covered. Just so you know, here are a few interesting facts about the lake.
The surface area is 31,700 square miles or 81,270 square kilometers and contains 2900 cubic miles or 12,100 cubic kilometers of fresh water, 10% of the earth’s fresh surface water. The average annual temperature of the lake is 40F (4.4C). I could bore you with more facts, but you can just look them up if you are interested.
This winter it is getting close to freezing entirely, but I don’t think it will. While the next few nights will be sub zero Fahrenheit there will also be a strong wind that will move the ice sheets around and break them into pieces. If you like ice in your drinks, this is a good time to go get a few shards for doing so. Be sure to get one you can actually lift and be careful you don’t get hurt or fall into the water. You won’t last long if you do.
It is fun and interesting to watch the changes, especially this time of year. This is about the time of maximum ice as it takes all winter for the surface to cool down enough to freeze, but with the days lengthening and the temperatures about to start warming up it is a fleeting moment in the overall scheme of things. That makes it fun for a geek like me to watch the constant changes.
The first one is Five Mile Rock which is, oddly enough, about 5 miles from town.
I live about ten miles from town, where I work, and about 7 or 8 miles of that is along the lakeshore. All the pictures in this entry are taken between home and work. I am also pleased to note that I don’t usually need my headlights on to go either to or from work now, although daylight saving time (DST) may screw that up a bit next weekend when we move our clocks ahead by an hour. Don’t get me started on that idiocy.
Here's one from the deck this morning. More open water due to the wind.
