Bona Mansio Island (bg|остров Бона Мансио|ostrov Bona Mansio, pronounced as /bg/) is the ice-covered island extending 750 m in east–west direction and 635 m in south–north direction lying in Papazov Passage, Biscoe Islands. The island is separated from the west coast of Krogh Island by a 700 m long passage narrowing to 50 m at points. Its surface area is 30 ha. The feature was formed as a result of the retreat of Krogh Island's ice cap around the turn of 21st century.[1]
The island is named after the ancient Roman road station of Bona Mansio in Southern Bulgaria.[1]
Bona Mansio Island is located at -66.2517°N -67.1069°W, which is 90 m east-southeast of St. Christopher Island, 2.55 km southeast of Talbott Point on DuBois Island and 2.55 km southwest of Edholm Point on Krogh Island.
