The Tateyama Kurobe Alpine Route, a 90 km snow corridor route that crosses Tateyama in the Japanese Alps, has become famous for Yukino-ōtani, a valley of snow with canyon-like walls that can reach 20 meters (66 feet) in height. The roads are carved out every spring with the aid of bulldozers and GPS to help find them under months of heavy snowfall.

The spectacle of this attraction can be hard to see from above by drone, but flying over the route is still a beautiful sight. Though it looks to be missing, the video is available. Click play:

And then watch this 2012 video from the road. Be sure to compare the bus and tourists to the height of the walls:
