Testing the Ice

Temperatures have been cold for the last week or so with lows in the single digits. Brrr. Ice is forming on the lakes and ponds but most of it is too thin for walking. We did find a shallow area of a pond that seemed safe. The bubbles in the ice were fascinating. I wonder if they are from the decomposing wood in the water below? We could see them in the middle of the ice and also where it looked like they were at the bottom surface of the ice. We guessed that it was about three inches thick. Farther out in the deeper area, it looked cracked and we avoided it. Some folks have said they could see fish and turtles under the ice but we had no such luck.
