Portholes in the snow.

Hoarfrost on the edge of a hole in the snow, with prairie grass beneath. The Leadership Center Prairie – Aurora, Nebraska.
Early morning hoar frost, calm winds, and a hazy sunrise got me out the door with my camera Tuesday morning. I found plenty to photograph, including frosty milkweed seeds, mouse tracks, and lots more. But it was the little windows in the snow that I couldn’t stay away from.
It appears to me that many of the holes in the snow were a result of radiant heat, caused by the sun warming up the plants sticking out of the snow. Regardless of the reason, they were sure interesting to look at – especially with the morning hoar frost tinging their edges.
Here are just a few of the images I came home with.

I assume many of the holes were caused by heat radiating from vegetation warmed by the sun?

Some of the holes were more like cracks…

All in all, it was a pretty nice morning to be out.
