Peculiar Geological Spots in Mt. Paektu Area (3)

3

The area of Mt. Paektu in Korea has many geologically peculiar spots formed by volcanic eruptions.

The extinct volcanic body of Soyonji Hill is a parasitic cone 10.5 kilometres southeast of the centre of the crater of the main Paektu volcano.

Parasitic cone is a small volcano on the slope or at the foot of the big volcano. It is formed when the main stream of lava moves or branches off.

The extinct volcanic body of Soyonji Hill is 2,114 metres above the sea level. It has a crater on its top.

The top of the hill is an alpine meadow. Azalea, Paektusan blueberry, and rhododendron are growing on its slope.

The valley is covered with snow and ice even in July and August, the hottest months in Korea.

The extinct volcanic body of Mudu Hill is also a parasitic cone which was formed at the time of volcanic eruption on Mt. Paektu. It is 1,930 metres above the sea level. It is standing in the northeast of Soyonji Hill.

The top of the hill is covered with pumice.

Pumice stones were piled up thick on the side open to the wind to form a gentle gradient and the opposite side is a steep incline without pumice.
Different kinds of alpine plants and animals are found in the area of Mudu Hill.

The extinct volcanic body of Mudu Hill shows volcanic bombs buried under pumice stones. Some places emit volcanic gas from underground.
