Site description (2001 baseline)
Extent of this site: to the east is Shih-chiao; to the west is Yieliu Fishing Harbor; to the south is Provincial Highway 2; and to the north is the East China Sea. Keelung City is about 15 km to the northwest. Yieliu is a promontory about 1700 m long which rises abruptly out of the sea, belonging to the Tatunshan Mts. The processes of erosion by the sea, changes by the wind, and crustal movements have created sea-eroded caves, channels, and hoodoo rocks shaped like hives, candles, tofu, and mushrooms, as well as platform caves and erosion pans, spread out over a large area creating amazing scenery. It is a valuable resource for geological scenery, research, and education. Because of this sites unique geographical position, after typhoons have passed or during migration season, this is the best place in northern Taiwan to see vagrants.
