Pond Ice Thickness, one day later

Posted by Kirk
Today the ice on the pond was 22 mm thick, yesterday it was 6. That's 16mm of new ice in one day. If you look closely at the photo, the old ice is on the right and the new ice on the left. The two hve a slightly different quality and bend the light differently. The new ice forms on the bottom of the old ice so my thumb is touching the bottom of the ice sheet and my pinky is on the top of the ice.

Below is yesterday's ice from the same spot for comparison.

That's pretty impressive growth. It has only been about 19° or so all day so we're making plenty of ice out there. Tomorrow is supposed to be above freezing.
