Sea Stack Landscape
Reference work entry
This landscape is composed of isolated columnar or tower-like landforms along a rocky coast. Sea stacks form when a coastal headland or marine terrace is eroded by wave action, and a rock pillar, which is separated from the shore, remains behind in the water and stands on the wave-cut platform. Sea stacks can also form from the collapse of a sea arch due to long-term marine erosion. Some stacks are in the form of an eroded mushroom. Sea stacks are common along China’s coastline. Typical examples include the Heishi (Black Rock) Reef in Dalian, Jiangnu (Lady Jiang) Grave in Suizhong, Yingjiao (Eagle Point) Rock in Beidaihe, Yandun (Smoke Pier) in Shandong Province, Shilaoren (Stone Old Man) in Qingdao, and ‘Nantian Yizhu (Southern Pillar)’ at Tianya Haijiao (Sky and Sea End) in Hainan Province. The Jiangnu Grave is composed of four individual stacks, the tallest of which is 16 m tall. The Yingjiao Rock in Beidaihe is 17 m tall (Fig. 17).
