Patterns in ice

At this time of year, I’m lucky to get in one good excursion per week, so I hope it is understandable that I’m making the photographs last through a week of blogging!
I loved the pattern of frost on the bridge.  It was late morning — nearly noon — when I took this picture and the temperature was just edging past the freezing point down by the river.

An hour later, the frost had been melted by the sun.


Below are four photographs showing four different views of the same pattern:

Which one of these four is your favorite, and why?
