I spotted this on our hike.
A very slow action shot.
We went for a walk around Squires Lake today. When we got there is was about 29F. It warmed up to almost 36F when we left at about 1:30. The ice we saw was incredible. The kids were fascinated with the crystal lattice expression of water, and the power it had to lift the surface of the trail two inches higher than when it was muddy. It really does remind me of finding halite in dry lake beds in the Mojave desert.
