In order for Tuesday’s dragline walk, enormous preparations had to be made. For instance, a gap in the power lines running parallel to Highway 83 had to be made. The machines are simply too tall to go under. The railroad tracks had to be covered as well.

Next, a compacted dirt road several feet thick had to be constructed. This served the purpose of protecting the paved road as well as creating a level deck for the scoop and draglines to traverse.

Crews worked from each side of Highway 83, meeting in the middle. Enormous excavators filled dump trucks, which deposited their dirt at the end of the constructed road on their side. Big dozers pushed it into place, and the biggest grader I’ve ever seen did the grooming.

A bed of shredded straw was placed on the highway prior to the dirt work, presumably to aid in the cleanup. This way the dirt wasn’t plastered onto the roadway below. I got to stand really close to where these guys were doing their dirt work, but at a safe distance. Of course I brought my hard hat, vest, and safety glasses with, and I had an escort the whole time to make sure I wasn’t too close.

With the road complete, it was time to get the “small” stuff across. The two machines in this shot are on tracks, simply driving across instead of the meticulous “walking” of the big dragline.

This equipment is electric, running with giant extension cords that lead back to the power plant. When they need to take a trek like this, the smaller ones are powered by a generator on a trailer. The truck follows dutifully behind or beside this scoop shovel as it tracks across.

For bigger equipment such as this tracked dragline or the big Chief Ironsides, they operate tethered to their usual power source. There’s a new power cable waiting for them on the other side.

This “little” tractor isn’t so little. Its sole purpose in life is to guide the electrical cable supplying power to the big dragline. It’s got a hoop-shaped guide on the back that is used to push the cable around to where it needs to be.

Now that everybody’s across, they’re working their way to the new mine site. Then it will be business as usual for at least another twenty or thirty years! There was a dedicated crew for this task; the rest of the mine’s operations didn’t skip a beat. Talk about a daunting task: close the highway, build a new road capable of handing a thirteen million pound load, get the equipment across, then remove that road…all within 24 hours. Great job, gang! That’s an impressive day’s work.

I’m so excited that I was able to be here for this occasion, since it isn’t going to happen again for a long time. It was cold and windy, but it was worth it. I had to park the Suburban sideways with the camera in the back, shooting out an open window, for my time stuff. The wind was just a little too strong. Thankfully I dressed really warm, and had a real blast! See you in twenty or thirty years, I suppose.
