The largely glacier-covered, 9 x 10 km Bristol Island is one of the largest of the South Sandwich Islands. Both summit and flank vents on Bristol Island have been active during historical time. The latest eruption, during 1956, originated from the west-flank crater, and deposited cinder over the icecap. The extensive icecap on Bristol Island and the difficulty of landing make it the least explored of the South Sandwich Islands.
