A pair of Carlile Kenworth T800's labor to get a heavy load up a steep grade, with the rear tractor, pulling a much lighter load, using its push bumper to give some assistance.
At the top of Beaver Slide this Carlile rig kicks up a fair amount of dust despite being slowed down by the steep grade.
Might as well stay back, because to try passing a truck under these conditions would be suicidal. Just when you are sure that there couldn't be any oncoming traffic, a semi or pickup shows up.
Evidence of the need to keep headlights on at all times on the Haul Road. The dust can be much worse than this in the dry season.
Being right in behind a heavy-haul trailer with literally dozens of tires, the poor pusher tractor gets a mud bath, as this one shows.
