The hill that drivers call “Koyukuk” is right next to the Koyukuk River and it’s one of the steepest on the Dalton.  It’s about 30 miles south of Coldfoot.  The video was taken last winter.

Jack happened to be there to document this huge mod being pushed up the hill by push trucks and also being steered from the back because it’s so long.  If you look close you can see someone standing outside on the load as it goes up the hill – he’s steering the rear end as it goes around the curves.  The guy doing the steering is one of the former owners of Carlile and he comes up the Dalton for these types of loads that need some special care.  (Carlile was sold to Saltchuk Corporation a while ago.)

In case you are wondering, the truck is going pretty slow, about 5 miles an hour in 3rd gear.  The last thing you ever want to do, Jack says, is change gears when you’re going that slow with that much weight since you’ll stop before you get it into a different gear.  If you stop it’ll take a while to get going again and without the momentum you’re putting a lot of strain on the truck and there’s too much potential for breaking something.  The years Jack spent in heavy haul were great years he says, but he doesn’t miss it.
