🔥 Aldeyjarfoss - The dramatic hexagonal basalt columns here were born 9,000 years ago, when the Bárðardalshraun lava field (part of Suðurárhraun) poured across the Icelandic highlands.
Steps in the formation of basalt columns:
1. Lava Flow: A volcanic eruption releases basalt lava.
2. Cooling and Contraction: As the lava is exposed to the air, it cools and solidifies, a process that causes it to contract.
3. Fracturing (Jointing): The contraction creates stress within the cooling rock, leading to the formation of cracks.
4. Hexagonal Shape: The cracks spread in a way that minimizes stress and surface area, naturally leading to a hexagonal pattern of columns.
5. Exposure: The rock face eventually shears off, exposing the perfectly geometric, hexagonal columns.
