I walked to the spring at the head of a stream that never freezes. The air temp was -9, I put the thermometer in the water for a couple minutes.
The water temp was almost +9, the reading started dropping as soon as I took it out but it was still above 8 when I got the photo.
These snowshoe tracks are mine that I made on Saturday, no need for snowshoes today. The snow was crusted enough to walk on just with boots.
