The unique formations are a result of lava flows cracking as they cool, in a perpendicular direction to the original flow.
Sailing stones
These rocks move when large ice sheets a few millimeters thick floating in an ephemeral winter pond start to break up during sunny days. These thin floating ice panels, frozen during cold winter nights, are driven by light winds and shove rocks at up to five meters per minute.
Penitentes
These intimidating snow structures are formed in high-altitude areas with low humidity, such as the glaciers of the Andes mountains.
Light pillar
A light pillar is an atmospheric optical phenomenon in the form of a vertical column of light which appears to extend above and/or below a light source.
