Mount Takahe is an isolated shield volcano in eastern Marie Byrd Land with an 8-km-wide summit caldera. The massive 780 cu km volcano displays a conical, youthful morphology, and the oldest dated rocks are only 0.31 million years old. Three samples were too young to date by Potassium-Argon, and some tephra layers younger than 30,000 years in the Byrd Station ice core are thought to have originated from Mount Takahe. Two early Holocene phreatomagmatic tephra layers in the Antarctic ice core were attributed to Mount Takahe (Palais et al., 1988). The latest stage of activity at Mount Takahe constructed cinder cones on the upper southern flanks and tuff cones and cinder cones on the lower SW and NE flanks.

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.

Takahe, Mount Shield volcano
A broad ice-filled caldera tops Mount Takahe in this aerial view from the east. The trachytic shield volcano rises about 2100 m above its base. Cinder cones and tuff cones are located on the flanks of the volcano, and outcrops in the center of the 8-km-wide caldera may represent the top of a lava dome. Gill Bluff, the prominent rock outcrop in the left foreground, consists of lava flows and flow breccias. Mount Takahe is the possible source of ash layers in Byrd Station and Dome C ice cores.

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.
