There's not many situations on the rim where you can canyoneer and do a packraft exit during snow melt, We recently did a first descent on this canyon, set anchors, named it (Leave it to Beaver) did 8 rappels and attempted a packraft exit back to the car. The situation is there with the proper CFS and the proper gear. We hit it at 140 CFS with the explorer 200's. (not recommended) A more durable packraft would get the job done and end with a 10 minute hike to the car. You can also just run the canyon and take the Bell trail back to your car at around a 3 mile hike out.
