Jeju Island, also known as the "Island of the Gods," is a beautiful volcanic island located in the southern part of South Korea. It is a popular tourist destination due to its stunning landscapes, beautiful beaches, and unique geological features. One of the most fascinating geological formations found on the island is the columnar joint.
Columnar joints are hexagonal, basaltic rock formations that form as a result of the cooling and cracking of lava. Basaltic lava is molten rock that is expelled from a volcano during an eruption. When the lava cools rapidly, it contracts and cracks, resulting in the formation of hexagonal columns.
found in Jeju Island are considered to be some of the best examples of this type of geological formation in the world. They are located in the Jungmun Tourist Complex, a popular destination for visitors to the island.
The columns are up to 20 meters high and 1 meter wide, and they form a natural amphitheater that is truly awe-inspiring. The columns are believed to have formed over 140,000 years ago during a volcanic eruption on the island. As the lava cooled, it contracted and cracked, forming the hexagonal columns that we see today.
The columns are not only a beautiful sight to behold, but they also have practical applications. They are incredibly strong and resistant to weathering, which makes them ideal for use in construction. In fact, the ancient Romans used columnar jointed basalt in the construction of many of their buildings, including the famous Roman roads.
Visitors to the columnar joint in Jeju can walk along the top of the columns and take in the stunning views of the surrounding landscape. There are also several observation decks located throughout the area that offer panoramic views of the columns and the ocean beyond.
In conclusion, the columnar joint in Jeju is a must-see destination for anyone visiting the island. This unique geological formation is not only a beautiful sight to behold, but it also offers a fascinating glimpse into the history of the island and the volcanic activity that shaped its landscape.
