The mountainous Tateyama Kurobe Alpine Route in Japan opens each spring flanked by towering walls of compacted snow, which slowly recede as summer approaches.

The route is carved through the snow and the “walls” on either side can reach 66 feet (20 meters) in height, according to the route’s website. In 2018, the walls were about 56 feet high in places, the Japan News reported, when the route opened on April 15.
