Oreum

[3] The word is now considered to refer to Jeju's numerous small parasitic cones (측화산; 側火山; also 기생화산; 寄生火山).

Their formation and preservation are due in part to the high permeability of the volcanic rock.

Oreum are classified as cinder cones, lava domes, fault blocks, or cryptodomes.

[1] Geomunoreum is located between Jeju City and Seogwipo, on the eastern side of the island.

This oreum is considered geologically interesting because of its significant lava tube system.

[8] The oreum is considered beautiful, with scenic views of the east coast of Jeju, including of the mountain Seongsan Ilchulbong and the island Udo.

It is on privately-owned land,[13] and offers views of Hallasan and Sanbangsan, as well as paragliding from the top.

There is a view that Saebel and Saebil are words in the Jeju language meaning "stars" but this is uncertain.

At the southern peak, there are ridges in the southwest, northwest, and northeast directions and there are 5 dagger-shaped mountaintops that look like a star.

Although it is only 382 meters above sea level, it has all of the characteristics of a volcanic terrain and is called a 'queen of oreum.

On the horseshoe-shaped foot of the mountain, there are debris slide layers as Dunji Oreum in Gujwa-eup.
