The 11 x 19 km Peter I Island in the Bellingshausen Sea opposite Ellsworth Land is a morphologically youthful shield-like volcano. A 100-m-wide circular crater is found at the summit of the 1750-m-high volcano. The island was discovered by the Russian explorer Bellingshausen in 1821, and extensive summer pack ice and its isolated location far from regular shipping lanes have restricted visits to the island. Dated samples from Peter I Island range from 0.35 to 0.1 million years old (Prestvik et al. 1990). The unmodified volcanic form of the upper part of the volcano argues that parts of it may be Holocene or even historical in age (LeMasurier and Thomson 1990).
