Penitentes

First of all, we are not making you look at a picture upside down. The spiky region you see in this picture is known as penitentes. Every piece is almost 4m tall. Such structures generally appear in the high-altitude regions like the glaciers of the Andes mountains. Sometimes, when the sun is bright enough on the top of the glaciers, it causes the ice to evaporate. well, this formation leads to even faster and wider evaporation.
