When I was an undergrad (with a geology major), I planned to become a glaciologist. Went to Alaska to study glacial ice and glacial geomorphology. One of my favorite books is Edward R. LaChapelle’s Field Guide to Snow Crystals.
I’m there’s an explanation for how these kinds of waved lines form. It’s like you threw a pebble in the puddle then flash froze the ripples. However it happens, I like it. Arrested motion, waiting for spring….

I like your wintertime series Denny, lots of subtleties. I think the lines might be called bights and are caused by wind perhaps rather than current? You may enjoy this link, the US Navy’s lexicon of ice…or it may bore the crap out of you (G) http://www.nrlmry.navy.mil/forecaster_handbooks/Arctic/Forecasters%20Handbook%20for%20the%20Arctic%20Appendix%20A.pdf
