It is a small volcanic cone with a cauldron-shaped circular crater on the side of the road at the southwest foot of Jeoji Oreum. In the village, the crater is called Gamechang because it looks like the bottom of a cauldron. It is located on the right side of the road when you go a little bit from the intersection of Jeocheong Elementary School in Jeoji-ri, Hangyeong-myeon in the direction of Sudong. You can see the crater by climbing a few steps up the hill where the pine trees are located. The crater has a circumference of about 300m and a depth of 16m, making it deeper than the slope of the outer ring, Vigo (6m). The Oreum is beautifully surrounded by a lawn ridge, and the moment you cross the stone wall leading to the isolated private house next to the Oreum, you cannot help but be surprised by the hollow ridge between the fine lawn and the sparse pine trees. The bottom of the crater is surrounded by a stone wall between the crater and the slope, and the inside is used as agricultural land.
