Tateyama or Mt. Tate but never Mt. Tateyama

The repetition makes sense to me because it works in both languages. Mt. Tate would confuse locals. Mt. Tateyama satisfies the need to make it "english" and also works in Japanese because they can just ignore the Mt. part.

But people are fine with Mount Fuji...

Incidentally, most people are also fine dropping the "Mount" prefix for Everest, Kilimanjaro amongst others...

Earlier quoted context omitted.

It's not remotely operated: > The GPS and sat phone work in tandem to provide the driver a detailed video screen image of the dozer’s location in relation to the center of the snow-buried highway. This driver’s job is not to clear snow, but simply to lay out an accurate track of the road itself.

Reading it again, I think you're right Makes me think though why could they not manoeuver it remotely with remote feedback if necessary, why put someone in the cab if they have it equipped with sensors. Some other heavy equip are operated remotely.

possibly, sensors have difficulty with snow? Low coefficient of friction, high reflectivity, differing levels of compressibility, difficult to judge slipping tracks, etc. Dead reckoning based on the track output probably doesn't work great.

Beartooth Pass in northern Wyoming is intense as well: https://www.youtube.com/watch?v=ZTdrGQiE5EM

I drove the beartooth highway this summer. IIRC, signs said it was closed all winter.

Yeah, typically opens in June and then closes at the first healthy snowfall, which is probably September.

I would love to see that first bulldozer at work. I'm a little amazed because snow becomes incredibly heavy and hard to move/push when it's packed. As the blade moves forward, that dozer will quickly have to use incredible force to move forward. I experienced this first-hand last summer when I was driving my old Land Rover across the country. I was solo, way up in the very remote Henry Mountains [1] of Utah, about to…

Your linked photo hardly looks like a road.

It's more of a trail. It's the northern pass over the Henrys, a BLM road. I got stuck right about here:

The top may be fluffy, but by the time you've dug through the top 50ft I doubt it's very fluffy anymore.

Compared to rocks, ice is not that dense. You can try yourself: it's easy to pickup a big chunk of ice, even with a shovel, while a similarly sized rock is impossible to lift.

And ice, quite surprisingly, is less dense than water. There are not many solids that are less dense than their liquid form.

Did the article claim the Japanese invented the snow-blower?

Have you even read the article? The headline already suggests "japanese style" even though it's just a common practice used for decades around the world. And the articles goes in great length mentioning a 600 horse power machine that is common elsewhere as well. And Japan was very well known for their "tourists" that took photos of everything oversees just to clone and rebuild it in their home country. (well nowadays…

It's the use of GPS followed by a fleet of dozers that's unique, as far as I can tell.
