I'm not going to take the time to go into detail about the new wood on the NF Nooksack, and will instead refer to the write up here.
However, I did want to put up this picture. This was the only mandatory portage at BONY flows (~300 cfs?), and it sneaks up on you quick. It is at the bottom of the long rapid above Bench Drop, and it is very hard to see until you punch the last hole, at which point you're better off heading to river left and fast.
