Several insets provide more information: a geological cross-section of the island, an outcrop map, a digital elevation model, a map compilation diagram, plus a map of the James Ross Island Volcanic Group with a table of the groups’ geochronology. The map is accompanied by notes and a list by a list of reference sources.
