Yongdae Gap[2] (Korean: 용대갑, 龍台岬, "Dragon-Terrace Cape") is a North Korean headland in the middle of the country's eastern coast along the Sea of Japan. It forms the southeastern corner of South Hamgyong's Danchon County and the western point of a narrow bay sheltering Songjin and Hwadae.

Names

In the 19th century, Yongdae Gap was known as Cape Schlippenbach or Schlippenback.[3] During the Japanese occupation of Korea, it was known as Ryūdai-kō.

Geography

Yongdae Gap is the southern point of a small peninsula whose most conspicuous summit is Wonsandok San, which rises to an elevation of 504 meters (1,654 ft) about 4 miles (6.4 km) due north of the cape. The highest visible mountain from the point is Yongyon San, which rises to an elevation of 1,598 meters (5,243 ft) about 17 miles (27 km) farther NNW. Its range extends 25 miles (40 km) north from the cape.[2]

A half-mile (.8 km) to the west of the peninsula is Yongdae Myoji ("Yongdae Anchorage").[2] This has a depth of 9.1–13 meters (30–43 ft) and bottom in fine sand, but is unsafe except as a shelter from NE winds.[2]

To the east of Yongdae Gap is a narrow but long and deep bay[3] extending about 40 miles (64 km) east to Musu Point.

Lighthouse

Yongdae Gap has a lighthouse, but it is closed to the public[4] and the American National Geospatial-Intelligence Agency notes that "the existence and operation of all navigational aids should be considered unreliable on the east coast of North Korea".[1]
