We continue to have above freezing weather during the day, dipping below the freezing point at night. The leads to a lot of melting and re-freezing on the creek. There are areas where the creek is entirely frozen over, and others where it runs free, except for a fringe along its edges. The ice itself is quite varied. Some is clear, some an opaque white; some has a dull granular texture, some is a palimpsest of crystals upon cyrstals

One thing that interests me is that a plate of ice that freezes will sometimes develop ‘keels’ — parallel sheets of crystal that project down into the water. I imagine, but could not verify because of where I collected them, that the sheets are parallel to the flow of water beneath the ice.
