A Pisten Bully. I got certified to drive one yesterday and they are pretty easy to drive, starting them can be a bit complicated though. It's an example of German engineering. Apparently pisten means "packed snow" in German. The ride in the back is pretty bumpy, but up front it's a lot smoother.
The trencher at the vehicle maintenance facility which was at one point at ground level.
The spool of cable at one end of the trench. We used a snowmobile to pull the cable out, and when the belt on the snowmobile started smoking we switched over to the caterpiller ditch digger.
A box of the ferrites. We put on about 500 of them. The cable carries the power to our instruments as well as the data coming from the instrument. The ferrite is there to suppress any high frequency noise. My boss would have liked to have ferrited the entire 1800 meters (a little over a mile) of cable, but I'm glad we didn't. We only ferrited about 500 feet.
It took the two of us four hours or so and was not much fun towards the end. The plastic cases started breaking in half on a few of them so we had to tape them on the cable. We had cold tested a couple in Hawaii and didn't have that issue and the freezer was colder than it was here.
The cable inside the trench. In the background, if you follow the trench, you can see the station. It's probably about 2 miles away.
