The Pliocene-to-Quaternary Gallego volcanics, comprising a group of steeply dissected cones, cover a large area of NW Guadalcanal Island (Hackman, 1980). Mount Roundhead is a small, but well-preserved volcano. Local traditions mention an historical eruption, but this could refer to an eruption from Savo volcano (1991 pers. comm. from Coleman to R W Johnson). The International Association of Volcanology and Chemistry of the Earth's Interior (1973) considered andesitic Mount Esperance to have been active during the past 2000 years.
The Global Volcanism Program is not aware of any Holocene eruptions from Gallego. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Gallego page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
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.

|The Pliocene-to-Quaternary Gallego volcanics cover a large area of NW Guadalcanal Island along the top part of this NASA Space Shuttle image with north to the upper right. Local traditions mention a historical eruption from Mount Roundhead, but this could refer to an eruption from Savo volcano, the island at the upper right. Mount Esperance volcano rises above Cape Esperance, across the channel from Savo Island. The city of Honiara lies along the northern coast of Guadalcanal Island at the lower right.

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.
