    How do they even know where the fuckin road is under 60ft of snow to say nothing of how they actually do it

        Yeah but those perfectly straight walls of snow make me question that. It looks carved.

        Either that or this magical thing called GNSS :)
        Openstreetmap has roads mapped down to a couple decimeters and Japan has its own satellite constellation QZSS, which in combination would be more than enough to find the center of the road and then slowly work your way outwards to the edges.

      Sometime in early March, a bulldozer specially equipped with both a GPS and a mobile satellite phone is sent up the mountain and over the Snow Canyon. 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. Following the GPS dozer is a team of dozers that will begin the clearing operations.

      That doesn’t all fall at once haha. They continually plow after every snow fall and add to the existing piles. How they manage to keep stacking and carving it so perfectly and so high is a mystery to me, but I’m sure the snow is only this high in this particular area. It’s likely an attraction or something
