we're within 50 meters or so, and we're going to hit this really steep stretch of river that we kind of anticipated might be at full two-day portage. >> the portage is basically a way around running a section of river. so you'll put your kayak on your shoulder and hike around that rapid. >> we hit this relatively short section of river, maybe only three kilometers, but it slowed us down to a crawling pace literally because we were like crawling over giant boulders, trying to portage sections of river that were completely unsurvivable. >> there's no point to even scouti scouting. when you see the gradient, you know it's not going to go. >> yeah. >> [ bleep ], [ bleep ]. >> hold on.
