Here is a couple of pictures taken at the boat launch at Alton Bay on 3-11-07:
A lot of water on the ice, some from the warm temps, and some left over from the rain last night.
This picture is of the area in the foreground of the above picture, and right below the arrow is a hole a couple of inches in diameter, and you could actually see the water flowing in and out of the hole (like current). Strange.
Suffice it to say, with some warm weather, the edges will start to get unsafe really quickly, so a word to the wise...
