I ran it tuesday solo for my birthday, I posted a video on the new years sho run thread. I tried breaking through the ice in the pool above man eater and it wasn't happening, I was hoping I would be able to ramp up onto the thicker ice and scoot to the other side but trying to get speed enough through the 20' ice channel wasn't happening and I was worried I was going to get stuck in the slushy channel or flip over and have to swim under the ice cause I probably wouldn't have been able to roll back over. So Yes Shoshone does freeze over and yes, as of tuesday it was frozen and portaged. The rest was pretty clear albeit shallow and starting to choke up in places (the middle slot on tombstone looked just about too tight so I did the ferry between new rock and wrapper).
Here's the video from tuesday:
