Always good to remind myself to enjoy the beauty of winter! It take so much less energy than complaining about the cold. Thanks to eMorphes for posting this on (for me) a cold winter day. Images by various photographers – check the original post for credits!

Extraordinary! Just think – if we found only the trackway, or only the roller, no-one would seriously believe the explanation! >
Yes, that’s so interesting – that al the elements & context are in many ways absolutely necessary to understand what’s going on. I remember that as a kid, when there were ‘exactly right’ snow conditions, I could make something akin to these snow rollers, and launch them down hills – had no idea until now why that worked!
