Updated picture

Remember the other day, I posted a picture of the Big Hole starting to ice over? Yesterday I started the truck around 3pm and wanted to drive it a bit to charge the battery. It had warmed up to a balmy 2 above. So I drove to the same spot and took another pic, slightly different angle.

The next 4 days are supposed to be sub-zero, down to -33 on Sunday. The ice will continue to thicken on the surface, but underneath it's flowing water, and has no place to go except downstream and upward, pushing the ice surface, causing fractures in the ice, and ice heaves. 

In a month or so, it could look like this (taken a previous winter).
