The largely ice-covered, 6 x 8 km Visokoi Island consists of a single stratovolcano, Mount Hodson, whose rounded 1005-m-high summit lies west of the center of the island. Numerous basaltic scoria cones were constructed on the lower flanks of the oval-shaped island, which is part of the Traverse Islands in the northern part of the South Sandwich Island chain. The youthful morphology suggests that volcanic activity has continued until virtually the present time (LeMasurier and Thomson, 1990). Possible eruptive activity was reported during 1830 and 1930, and the summit is usually obscured by "smoke" or steam.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

|Glaciers descend the steep southern face of Visokoi Island from the flat-topped summit of 1005-m-high Mount Hodson. Wordie Point (left) and Irving Point (right) lie respectively at the west and east sides of the 6 x 8 km wide island. Numerous basaltic scoria cones were constructed on the lower flanks of the island, which is part of the Traverse Islands in the northern part of the South Sandwich Island chain. Possible eruptive activity was reported during 1830 and 1930, and the summit is often obscured by "smoke" or steam.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
