Yeolanjigeorum (Bonggae-dong)

Yeolanjigeorum (Bonggae-dong) is a parasitic cone located in Bonggae-dong, Jeju-si, standing at a height of 328.7m. Its name was given because its shape resembles a flock of geese flying in formation. The northern slope is covered with a forest of black pine trees, while the southern slope consists of grassy fields. The crater is believed to have once been horseshoe-shaped before being eroded.
