Kuei-shan Tao TW
Kuei-shan Tao lies off of the eastern coast of Taiwan. It is also known as Turtle Island. A brief scan of the internet lists the island as a volcano.
Kuei-shan Tao (24°51'N., 121°57'E.), about 10 miles SSW of San-tiao Chiao, is a steep-to, precipitous volcanic island having a group of sunken pinnacle rocks about 2 miles to the SW. White vapor rises from the S shore. Sulfur, rising from the ocean floor, discolors the water to the S of the W extremity of the island.
From N and S the island resembles a tortoise with the pointed summit at its E point resembling the head and a pebble bank extending W from the W end of the island resembling the tail. A light is shown from the W side of the island.
Vessels anchor, in depths of less than 20m, sand, in a position about 0.3 mile off a small village at the head of a small bay on the NW side of the island. A prohibited anchorage, best seen on the chart, surrounds Kuei-shan Tao.
TURTLE ISLAND "This small, solitary island located about 10 kilometers off the coast of Toucheng in Yilan County has volcanic terrain that, from certain angles, looks like a turtle floating in the sea. Among the features of the island are high cliffs, steaming fumaroles, welling underwater hot springs, mountain peaks, sea-eroded caves, a lake, and unique cliff vegetation, as well as rich marine ecological resources. It is a perfect place to study volcanic terrain and the natural ecology."
