I have a rope for you but considering: 1) silk degrees apparently never complety forms, 2) Salmon stakes is hardly a grade 3 especially if the tube is 3+, not really worth ever going back for, 3) there are no trees worth tying in to or rocks for that matter, 4) I got soaked to the bone with slush in my toes and so should every one else!!
it may not be worth the trouble
Fern: first we tried to cross up river rock hopping, I fell in on the first rock hop since it was ice covered and we realized we needed to wade. We didnt go back to the salmon bar since we were now too far, so it was fairly deep. On the way back however we chose the salmon bar which was just as deep but had nice rocks to walk on.
This time i just wore my boots, which are now rotting on my heater at home.
