Cape Wollaston is a cape forming the north-west extremity of Trinity Island in the Palmer Archipelago of Antarctica. The name was originally applied by the 1828-1831 British Chanticleer scientific expedition led by Henry Foster. It was named for William H. Wollaston, commissioner of the Royal Society on the Board of Longitude, 1818–28, which loaned astronomical instruments to Foster's former ship, the Conway, for astronomical and pendulum observations (an objective of the Chanticleer voyage).
Important Bird Area
Cape Wollaston has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large breeding colony of about 10,000 pairs of southern fulmars. The 129 ha IBA comprises the ice-free land of the cape. It has an elevation of about 250 m.
