Shadow frost

Here is something I found that I thought was visually interesting.

The sun as it came up Sunday was melting the frost as it spread across my lawn, as the sun moved across the sky, only the shadow saved a small tree shaped patch. But the relatively low on the horizon winter sun was moving quickly and here if you look close (again click on the image) you can see the offset as the shadow has moved.

Like a relentless advancing army of solar rays, sent from millions of miles away, marching across the blades…you know its only a matter of time until all the frost is gone. Here for a short time, you could see what was left.
