Get out and scout at the first horizon line in the gorge. Look at this rapid carefully. There's a slot in the middle where a lot of water goes. Good boaters have lost their paddle by accidentally dropping into it with their shaft perpendicular to the crack. Worse boaters have gotten flipped backwards in it and swam. Such things are not recommended as a 100 yards downstream is a waterfall where if you deviate from an exceptionally thin line you will fall 25ft onto bedrock.
The line is to boof from the far left onto the bedrock sloping into the crack, ferry across this slope and then boof again below where the crack opens up. It's a really fun and unique drop. Portage right. Scout left.
