You are in a canyon. You have overnight gear, since this is a 2-day adventure. You have ropes since there is a 200' rappel up ahead somewhere. You have two competent people. The canyon narrows to a squeeze-through type canyon. You start to squeeze through and realize that while you just barely fit, your pack definitely does not. You can see the canyon drops 20 feet into the dark ahead, something you are pretty sure you can safely downclimb. Ahead of that, you can see it opens out, then turns into a 5 foot wide corridor with a flat sandy bottom for at least 20 feet. One person climbs over the top and as far forward as is safe. Below that point, the canyon is still too narrow for packs. What do you do?
