Answer:
The Triangular Face is the path taken by hikers when climbing the Mount Everest, the highest peak of the world. The reason why it is safer to hike this path in the dark is because there are less chances of the terrain changing. At night, the path does not melt or change drastically.
This makes it easier to walk and trek on this path. This does not happen in the morning when because of the rays of the sun, the pathways may melt and therefore force the hikers to take a different route or path.
