I did a 3 day trip above floodstage (3800 when we put on still rising) few years back ( Northgate canyon website, rates rapids up from class 3 to 4, over 3000k..Also the named rapids just become one, 6 mile rapid at that stage) Kayaker caught micro eddy to scout last rapid/falls, and watched me surfing,/ highsiding as my 15'sb climbed left wall!
(ask anyone, I always provide the entertainment on privates; nary a passenger got a hangnail through 25 years pro. guiding!)
Anyways, you can go past first take out, and do a 2 or 3 day to much easier takeout. Was really nice little trip for two (or more).
